Thanks! I think I would opt for the 2 slot version since I already have a functioning 4slot unit. I'm comparing the two now to make sure that's the only difference.
EDIT: Nope, not the same. So, now I'll debate if it's worth $33 for an extra 2A of charging power. Again, thanks

EDIT2: Regarding dosing capsules v2 from TM - I loaded all 5 up last nite for a poker game at my brothers house and carried them in the tube that they came in. Loading them is kinda cumbersome, but the ease-of-use they provide is great. They worked very well last nite, but I wanted to mention that I took the advice I read somewhere above (can't remember who it was that mentioned it), but I popped the top off of a capsule and put it in my Grav Upline Taster with a flat screen and it worked GREAT! I think when I am on the go now, I'll just use it that way. I definately prefer the TM2 without the capsules when I can be casual about vaping, but when on the go, I think I'll be using the capsules sans lids going forward.
