Compatible with 901 ????

Yea - the 510/dura carts do fit on a 901, but it's such an easy fit that if you lean forward the 901 battery and atomizer fall out! Also, the cotton seems to get stuck on the 901 atomizer every single time.....

That's really odd - my Dura carts fit perfectly and snug. Nor does the cartridge material get stuck. Perhaps it's a question of a slightly different size of the carts I bought, or whether we're talking about 901 or 4075 atomizers?

I wonder why carts for 901s dont just come bigger? Seems a simple solution....does anyone know if penstyle cartridges fit on a 901 atomizer?

That's a definite no. The penstyle atomizer has it's mesh bridge inset much further into the tube than the 901 style. Plus, it's a wider diameter than the 901 as well. So the penstyle cartridge would not fit in at all.
