The Billow v2.5 has the same unique exterior design as the Billow v2 that you all wanted us to bring back with some improvements to its overall functionality. Featuring a 24mm diameter base and top cap with the glass tank section tapering out to 25mm, the Billow v2.5's 6ml tank capacity can be conveniently top filled by removing the threaded top cap. Adjustable juice flow control has been implemented on the base of the chimney to prevent leaks and/or over-saturation of your wicks. In addition, the trendsetting 2 Post Velocity Style deck has replaced the original 4 post deck of the Billow v2 which makes building and wicking much easier.

    Best tank

    Posted by Braddahbill on Apr 21, 2021

    It's 2021 and this tank is still in the top of my rotation. I have bought many tanks but the Billow V2.5 is special. When built with duel coil single wire Kanthal and wicked correctly gives a smooth restricted direct lung hit. I have 2 brand new in box just waiting to be used.

    Keep this Tank in your line-up

    Posted by HOJO on Jan 01, 2021

    This is without a doubt the the best tank I have ever owned, a total of 5, 2 still in the boxes. It may take more time to get it wicked correct but the reward is well worth the time. 2.5mm/ 26 GA / 316 SS / 7 Wrap coils. I run in temp. control, best flavor ever and coils last well over a month, no problem. ENJOY!

    I can't say enough about this tank. Very ergonomic and user friendly. Perfect example of form and function. They don't leak either. I own two, and use them daily. Fantastic tank!!!!

    Great no BS workhorse

    I love this tank!! I find it to be superior to the V3 in every way. It was a little finicky to wick just right, but when you do it's a solid performer with good looks to boot. Highly recommended!!!

    Billow 2.5

    Posted by pegasus on Jul 14, 2018

    The build deck is very small I could not get 3mm coils to fit so i put 2.5mm coils in it. For a 25mm atomizer you think you could get 3mm coils in it. Then I had to trim the wicks a lot to get them to fit. The flavor is good and so far has not leaked. It does hold a lot of juice but because of the small build deck I would only give it 2.5 to 3 stars out of 5

    Great RTA but the build deck is to small.

    Posted by Jerry on Mar 13, 2018

    I bought this RTA because i wanted something with a large capacity and top fill not side fill like the V3 Billow. The machining is beautiful as well as a great looking RTA but the build deck is way to small. I purchase pre-made coils for my RTA's but they wouldn't fit and I had to make hand made coils so they would fit. The RTA is working great and looks great. I just wish they made the build deck bigger.

    Flavor land

    Great flavor RTA. You don't even have to use claptons to get great results with this it's built so well. At $23, it's a steal. I will be buying more of these.

    Probably the best engendered.

    I will always buy the 2.5 billow. Not only is the flavor great on the fresh cotton change but it's the zero leaking engineering that went into this design that makes it and excellent buy. When you install the lid after filling the juice vents open and when you unscrew the top for filling they shut. I love the thought that went into this tank. My Griffen doesn't hold a candle to it. I have two 2.5s on two mods as a precaution in case I drop one. I suggest you find a rubber type washer to fit over it to protect it.
