Monday I ordered a PCC kit from Madvapes and got it today. I'll use it for the next week or so for a full analysis but so far I really like it. I do have a few 510's that I got from Indy Vapor, Bauway type, that are just a bit to tall to fit but that's no big deal. I can carry 4 batts with two rotating on the PCC just fine. That will also give me justification (excuse) to buy a box from Vapeboxz next month. The great thing is that I asked MadVapes to switch out the tobacco juice since I have lost the taste for tobacco with something sweeter like Vanilla Latte or something of their choice. I open the package and there is some wonderful VL waiting for me! Another satisfied customer.
