Day four of vaping here. Day three with no analogs! I got the 510 starter kit for my wife and I, then split it up to see if we would like this. We do and I've been ordering more parts to have on hand. I ordered a pink atomizer for her and a blue one for mine to help differentiate our 510's. (We both had all black ones) I've ordered a pcc for her, a second batt for me and some new flavors of e-juice to try. Car chargers, empty carts, etc.. The atomizers came from a different company (than where I bought the kit) I found through this forum, and it seems that the pink one for her produces next to no vapor. I tried dripping, different carts and both batteries. I put the first black atomizer back on and voila! lots of vapor again. The question, I guess would be this, are there different mfgs for 510 parts? I would think that only Joyetech would make them, but there seems to be a difference here. Or is it possible we just have a bad one?
