I have a REO, REO Mini, and 2 Phidias "auto or bottom" feed mods, and after a friend of mine's problems with his, and after doing a "search" here on ECF and reading what others say about leaking and bad switches, I would not recommend a WetBox to anybody, even people I don't like. Do a little more research before you hit the "Buy" button. All of my "auto" mods work great - without any hassles - and I wouldn't part with them. All of them will get me through 1 to 2 days of vaping, without the hassle of refilling a cart or cartomizer and having to carry a bottle of juice around, without scrambling around for paper towels to clean up the mess, and without worrying about a battery going dead on me - a wonderful sense of freedom. I use 510 and LR510 attys in mine and have never lost one in the past couple of months. I also don't use carts or cartomizers, so that is a another expense I don't have.
