One of the most popular flavors in the e-cigarette world is RY4. This full-bodied tobacco flavor includes sweet hints of warm caramel and smooth vapor finish. An unforgettable flavor for sure, and our blend is an instant fan favorite.

I like it but smaller size makes no sense. I know it's about the law but makes it more attractive to younger users.
My go to flavour review by Darren on 7/24/2017
Apollo have in my opinion the best flavour RY4, I have tried other brands and nothing comes close. Very smooth and great taste!
Wanted something smooth and understated with no nicotine to mix with other flavours that have nicotine review by Trusted Customer on 6/21/2017
Wanted something smooth and understated with no nicotine to mix with other flavours that have nicotine if I needed to. This was the perfect choice, great alone or mixed with other flavours. Will be getting both nicotine and no nicotine versions next order.
This ry4 is excellent, as good as anything i've tried before, i'll be ordering more when my present stock review by Trusted Customer on 6/7/2017

My Choice review by Darrell H on 4/19/2017
I've tried other flavors but, this has always been my favorite. Nice and mild and very satisfying.
I really like the taste of this liquid as I have not yet learned to like the fruity flavors. It has a review by Trusted Customer on 3/20/2017
I really like the taste of this liquid as I have not yet learned to like the fruity flavors. It has a mellow tobacco flavor which hits the spot for me.
The Best review by e301 on 3/17/2017
I keep coming back to this stuff: every now and agin I try something different, from Apollo or elsewhere, and always go back to this. It has none of that chemical edge I find in almost any other liquid.
Excellent review by Trusted Customer on 1/18/2017
Favourite 50/50 flavour! review by adzam016 on 1/6/2017
Although it's kinda sweet, the mixture of flavours is done well enough that that's not a problem. Really nice flavour!
Great flavour review by Safa on 10/6/2016

Great all around device review by Steve M on 6/10/2016
I was a little timid on getting this kit as the price was a bit on the high side but there are no regrets so far! This mod fits great in my hand and hits like a Mack truck. The battery charger that comes with it charges fast - major plus.
Very happy with this device!
A+ Eliquid review by Ritchie on 4/11/2016

Best RY4 review by Michael Metcalf on 2/12/2015
My daily vape ...everyday !
Outstanding RY4! review by Karen on 2/6/2015
I won a bottle of this RY4 in a FB contest.(Thanks, Apollo!) Had to come back and get a big bottle. I've been vaping for 5 years and for me, this is the best RY4 out there. Really great tobacco flavor and caramel. It seems to have a hint of molasses which makes it even more enjoyable. Great TH and clouds. ADV for me....never got tired of it like I have with other juices. Just get it...I think you will love it. too.
Not too sweet review by Anne Carrick on 10/5/2014
This has a nice blend of tobacco and caramel. The finish is sweet, but not too sweet. The liquid does taste alot like the standard tobacco, but it's not as sweet as that one. I would order this again.
Amazing review by Stephen Mills on 6/7/2014
Can't believe I never left a review for this liquid. It is by far one of the best I have ever tried. Has an amazing caramel taste. I have been vaping it daily for two months now and still cannot think of a single thing wrong with it. It is one of my all day vapes for sure.
sweet and subtle review by Nick on 4/6/2014
a nice light ry4 that can be vaped or mixed with other flavors.
the bottle the liquid came in absolutely rocks!! the dropper tip is perfect for filling tanks
shipping was fast. i ordered wednesday night and got it in the mail saturday (3 days)
4 stars for the flavor of the liquid. im adding the extra star for the fast shipping, the promotional offer, and also the nice bottle
This is it! review by Brent Murphy on 3/28/2014
I've tried a handful of E-liquids and I must say than none have compared to this flavor. I've been trying to find a go-to flavor that I can vape day after day and not get tired of, this is it! This is so smooth, but also has a delicious rich flavor. It tastes like perfectly flavored tobacco with a mix of caramel. I'm so happy to have given this a try. It's now the only blend I vape. I highly recommend!
Happy At Long Last! review by Therese Kibbler on 1/7/2014
I just received RY4 today, and I am VERY pleased! I have tried several different e-juice flavors, and NONE have even compared to RY4! Very smooth taste, with just a hint of caramel. Love it! I have finally found the right flavor for me!
Awesome! review by chris corder on 11/29/2013
Vanilla, Caramel & Tobacco all rolled into one. I've not come close to any juice tasting like a cig, but this is the closest I've come. I love this one! Just the perfect amount of vanilla and caramel, make this another one of my favs. Sent some to my daughter, and she recieved it today, and she loves it!
My favorite review by Judy on 11/9/2013
Just received the RY4. Holy mackerel!!! This one is so tasty. The only way I can describe it is, tobacco, vanilla, caramel flavor all rolled into one e liquid. It's so good, I have to use the 6mg nicotine level or I'd be taking in more nicotine than I want. Try this one...you'll love it!!!
Innovative review by Tom on 11/2/2013
I have only tried two liquids. I like this one a lot. It is almost sweet, but still tastes like a tobacco cigarette. Leaves a nice taste in the mouth and lets off very little smell. Can't think of a cigarette to compare to it but it satisfies the urge and pleases the taste buds.
LOVE IT, my first, last, and always! review by Lisa Lampman-LaBelle on 11/2/2013
This is my favorite, and always will be. It's the first e liquid flavor I ever tried, and to date is still my fav after trying about 25 different flavors. Love the slight sweet caramel with just a teeny tiny hint of vanilla. I vape this one 90% of the time.
My favorite, hands down review by Mike F on 11/2/2013
This was one of the first e-liquids I tried and I love it. Tried some RY4 from a few different places after reading great reviews about them, but none of them were as good as Apollo's even after weeks of steeping. About to order another 30ml bottle right after writing this review.
The best !!! review by Anthony Cirullo on 11/2/2013
Tony AKA honestvape here. I have done a few reviews on different Ejuices and tried a bunch. This is my favorite RY4 to date.
first juice, still my favorite review by c.wargo on 6/17/2013
i must have lucked out when i bought this as my first juice, as its still my all day vape. nothing in here is overpowering. everything is blended very nicely. you get the tobacco, caramel and vanilla in a great tasting, and esp. great smelling vape.
would love to see the option for additional flavors, or maybe an all VG version for people sensitive to PG, because more people should experience this fantastic juice. you guys have made a real winner with this one.
Superb!! review by Alex on 6/17/2013
Awesome flavor, great vapor, is a daily vape choice for me, can taste a sweet and smooth carmel flavor. Very Good.

What are the ingredients in Apollo’s e-liquids?
All the Apollo e-liquids are made in our state-of-the-art ISO 8 Certified cleanroom facility in Livermore, California.
Apollo’s e-liquid mixologists are not just avid vapers and flavour gurus, they are also experienced chemists with BSc or PhD degrees. Unlike other e-liquid producers, our facility adheres to good manufacturing practices commonly found in the food manufacturing industry. This means a strict protocol and procedure is practised throughout the entire manufacturing process, from recipe development to bottling, to ensure a consistent quality. Apollo e-liquids are guaranteed contaminate free.
We take great pride in the quality of our ingredients. All flavors are made with:
USP Grade PG and VG
Food Safe Ingredients
Laboratory Grade Nicotine
Why does my e-liquid change color over time?
E-liquid can change color, sometimes even before you open it, as a result of oxidation (common chemical reaction). E-liquids containing nicotine may change their color when they are exposed to air, light or heat, and sometimes even when they are kept in cool, dark places.
If your e-liquid turns darker inside a clearomiser/tank and you get a slightly burnt taste, it’s time to replace your coil with a new one, throw the burnt tasting e-liquid out, and wash your tank under warm water (let it dry completely before vaping again).
Clearomizers / Tanks / Coils
How do I know which tank is compatible with a certain battery?
The first thing you have to check on both desired vape components is the threading. Threading available on the market fits 2 main categories – 510 and eGo, but most of them come with adaptors so you can easily switch from one to another. Secondly you should always verify the resistance of your coils is compatible with the battery you are using, so that you don't overload your battery. If you have any questions or concerns about this, please speak with our Customer Service Team.
What coil should I choose?
Coil (atomizer head) resistance is measured in ohms and comes in over 1.0 ohm and under 1.0 ohm resistance for sub-ohm tanks. The lower the resistance of the coil, the bigger the generated wattage, meaning your coil will get hotter and generate considerably more vapor. If you are using a sub-ohm resistance coil, always make sure the battery you are using can handle the lower resistance.
What is a coil’s lifespan?
The lifespan of a coil head greatly depends on usage, the e-liquid, and the style of vaping. It can be anywhere from a couple days to a few weeks.
When should I replace my coil?
Coil heads need to be replaced when you start to get a burnt taste and your tank produces less vapor.
What can I do if my tank is not working?
This usually happens right after you have changed the coil or refilled your clearomiser/tank. You have to check that your coil is in a good working condition (if not, replace it with a new one), that the coil head is tightly screwed in (finger tight is enough), and that your tank is correctly reassembled. If you are still having trouble, please contact our Customer Service Team.
What can I do when my tank leaks?
Leaking can be caused by many factors and can typically be resolved quickly. Please contact our Customer Support Team for assistance.
How long will a battery last between charges?
It is important to know how long your batterywill last between charges. You should pay attention to the battery capacity which is listed in mAh (milliampere-hour). The higher the mAh rating is, the longer the battery will last. Roughly, we can say that 100 mAh equals 1 hour of usage.
The mAh is a good guideline to follow in regards to battery life, but it is hard to say exactly for how long a single charge can last (as it is greatly influenced by your style of inhaling, the surrounding temperature, the resistance you are using it with, etc.).
What does pass-through mean?
The pass-through feature means you can use your battery even while it’s charging.
What are the variable voltage (VV) and variable wattage (VW) setting about?
Basically, voltage is the amount of energy in a device and wattage is the amount of work that is done in a unit of time. When you are using a device with VV settings, you are telling it to send a certain amount of energy through the circuit. When it comes to VW settings, you are telling your device how much work to do, and the vaping device figures out the voltage needed to overcome the resistance (based on coil head).
Why should I choose an advanced battery/mod?
The most advanced batteries (usually known as mods) are more powerful and feature wattage and/or temperature control for an enhanced, fulfilling, and customizable vaping experience. There are a wide variety of coils tand tanks they are compatible with, and you can adjust their settings until your reach the kind of flavor, throat hit and the vapor production you are aiming for.
What are 18650 batteries?
The 18650 battery is a versatile rechargeable accumulator meant for internal use, being the vape industry's battery of choice for most of the box mods on the market. 18650 batteries have a great lifespan and a wide power output. Apollo sells only the best authentic brands available. Please note: 18650 batteries require an external charging unit.
PLEASE NOTE: As of November 22, 2015 our Warranty Policy has changed. All purchases made on or after this date are subject to the revised Warranty Policy outlined below. If you have any questions please contact our Support Team at email@example.com. Warranty Replacements can only be honored by our Support Team if the product was purchased from us via this website, and you can supply your order information. If you purchased your Apollo product from one of our authorized retailers you must redeem your Warranty through that retailer.
Apollo offers a Six (6) Month Limited Warranty on all Apollo branded electronic components (including batteries, chargers, and mods). This warranty does not apply to 3rd party products not made by or branded with the Apollo logo. For a period of Six (6) Months we guarantee that your Apollo product will be free from defects in material workmanship under normal use and service for the product’s lifecycle, according to product usage documentation. This warranty does not cover any defects or damages on products that have been lost, misused, improperly or inadequately maintained, or modified. The warranty lasts for a period of Six (6) Months from the date of purchase, however products are limited to a maximum of five (5) replacements on any given item. The item must be ruled defective by our Support Team and will be replaced with an equal item from current inventory. Replacement or upgrade of product is your exclusive remedy under this warranty.
Apollo offers a Thirty (30) Day Limited Warranty on all 3rd party electronic components (including batteries, chargers, and mods). This Warranty applies to products not manufactured or branded by Apollo. For a period of thirty (30) days we guarantee that 3rd party products purchased from Apollo will be free from defects in material workmanship under normal use and service for the product’s lifecycle, according to product usage documentation. This warranty does not cover any defects or damages on products that have been lost, misused, improperly or inadequately maintained, or modified. The warranty lasts for a period of thirty (30) days from the date of purchase, however products are limited to a maximum of two (2) replacements on any given item. The item must be ruled defective by our Support Team and will be replaced with an equal item from current inventory. Replacement or upgrade of product is your exclusive remedy under this warranty. 3rd party products typically include a manufacturer’s warranty, in which case you must directly contact the manufacturer of the product for warranty replacements.
Apollo offers a Fourteen (14) Day Limited Warranty on all clearomizers, tanks, cartridges, replacement coils and cartomizers. This warranty does not cover any defects or damages on products that have been lost, misused, improperly or inadequately maintained, or modified. Using e-liquid that is highly acidic or contains cinnamon will void this warranty. Clearomizers, coils, cartridges and cartomizers are intended to eventually burn out and be replaced, and there is no perfect measurement scale for how long they will last due to a variety of factors. Everyone uses these products differently, and we cannot control for all variables. Recent industry quality studies have shown that if an atomizer works properly the first time it’s used, there is little reason other than improper use for it to stop working properly. We cannot warranty these products for a period of more than fourteen (14) days, because many of them only have a lifespan of fourteen (14) days.
All sales of e-liquids, disposables, and Rebuildable Drip Atomizers (RDAs) are final. Apollo does not accept returns or exchanges of these products and does not offer a warranty for them.
All warranty exchanges require preauthorization and must be accompanied by a completed Return Merchandise Authorization Form (RMA). To obtain authorization and an RMA Form, please contact customer service via online chat, or email support ( firstname.lastname@example.org), or call customer service at 855-2-APOLLO (855-227-6556).
Apollo reserves the right to revise or modify the terms of this warranty agreement at any time for any reason without prior notification.
