My girl is killing eGo type batteries at a rate of about 1 every 10 days or so. I got her a new charger so that's not the problem. She just won't put the thing down!! She routinely will hit the 10 second time-out. I've had to make sure she had 2 to 3 on hand at all times so she could have 2 on the charger while she vapes. 650, 900, 1100, all toasted. Last time I got her an iTaste VV V3, thinking maybe a little better quality (and USB pass-thru) might help. Nope..... For a while she was able to return them for replacements, but now all the B&M lock the doors when we pull in the parking lot (3 so far)..... I think she may have killed my MVP, too. Now when I try to charge it, it just blinks like a Christmas tree. Problem is that she doesn't want to step up to anything bigger than the eGo size batteries. She wants something cute and petite. She'll use my Sig 8 and MVP in the house, but she has to use 2 hands. Are there any mods out there that use smaller diameter batteries?? She doesn't even like the Sig in midget mode. Too fat and heavy... I'd like to find a mod that would fit her size preference and just get a good charger and a handful of batteries and be done with this for a while!!
