Hey was wondering if someone could please help me with this. I have a classic penstyle (matte black) from puresmoker, I love it, so I decided to order some backup atomizers. The only place I could find that had them in stock was myvaporstore, and they have been awesome to me so far, so I ordered 4 of the 801 atomizers. I may be wrong, but I thought that the puresmoker classic pen was an 801, the atomizers (and blank carts) from myvaporstore look a bit different also, but seem to fit well. I was wondering if someone could please reassure me that they are compatible and that they will work together well, as sooner or later the orig. atomizer will burn out. Thanks in advance for any advice!
