With either I can vape 6v or 7.4v but much of the time I don't want to use the extensions. I find I can get pretty much the same vape if I use the LR attys. Mostly I see 510 LR attys. Can anyone recommend where to buy the 901s and also, without attaching them to my GG .. Is there a way to just look at the atomizer and know if it is a LR or regular 901? They all seem to look the same to me.
