I just received my Roller today. I'm blown away by this thing. It's basically the definition of perfection. I got it in ice matte and this looks beautiful. I think I like this more than my Provari. 18350 mode is tiny. Very comfortable to use. And it's the smallest 18650 mod I have. Theoretically it could be a bit smaller but then it might be too small. And the button feels great. Very easy to push and has some nice solid feedback. Very well build and durable but still relatively light weight. Cheaper than most mods of this caliber too. I just need to find a tank that looks perfect on it. The Terminator and Richman rba go well with it. I highly recommend this mod!
