Great choice and overall exceptional value for the cost ! The telescopic arm is not very long but long enough for use with a gopro Very comfortable to use, a great mix between lightness and sturdiness

With these you can store and carry your atties - RDAs with the 2 blue foams and medium sized RTAs (like KF prime) when 1 foam is removed. You can also carry longer full size RTAs removing the 2 foams and expanding the length. Not 100% hermetic - if your atty leaks, most of the liquid will stay within the box but some can leak a little bit when turned upside down: the top cover is not sealed agains the bottow one, there is a tiny gap all around that allows leaks (and that allows air to go out, if it was not there you would not be able to close the box...)

For me a better choice than the insider which is a lesser build quality and more sensitive to the wicking Wicking is a breeze: insert the cotton, close the chamber, cut cotton 2mm away, expand it a little bit with the tip of your bottle while pre-feeding the wick and voilà ! Never ever had a leak or dry hit with it. Wick holes seemed big to me but are properly closed off if you throw in a 2.5mm coil. In terms of airflow: good for me, wide open it's still good for an airy MTL or restricted lung hit - it's not that much open as some say. And you can close it down but not as low as your MTL hyper tight atomizers of several years ago. 2 Negatives: 1. The chamber is a little hard to remove (easier when mounted on a test firing mod) - take care to lubricate the o-ring with juice in order to prevent cutting it and ease the disassembly when re-wicking 2. The 510 thread is very very short (less than 1/2 turn) - it's difficult to mount on some mods for test firing, you have to push hard and turn to catch the thread - the insider has for him an almost regular thread which is much more convenient

Overall very good product in replacement of the good old unicorn style bottles. Allows for one handed operation which is ultra convenient. Not having to handle a detachaple cap is really neat. Is really leak proof, no issues with that. Downsides are you always have some juice left at the point of the tip you have to wipe. The point is a bit big which makes the filling of some tanks more challenging - but still do-able. Unfortunately you can't pump back excess liquid like you do with other bottles. I wish the bottle's plastic was less firm because some marks appear on it.

For me the best option I tried between hellfire exocet, insider V1 and Flow TI from odis. The best because of the perfectly tunable MTL airflow, no condensation and no leaks. It's a bit bulky but also the easiest to build compared to the other RBAs I reviewed. This one made me stop looking for the perfect RBA match for my BB.
