DSE-901 tight... please advise

[georgini]

i had a batch of carts from litecigusa that did the exact same thing, they also had a single channel for air flow where my others had two channels. the boxes are also different, the ones that work have the little dude smoking and the tight ones have a thumbs up symbol on them. Also the ones that do not fit have blue printing on the clear packaging. I have several models of atomizers and they all were about the same.

This issue is probably the DSE901 vs DSE901b vs RN4075 vs OtherNoNames... all interchangeable but yeah, carts aren't exactly the same switching around. Same issue exists with carts for various interchangeable penstyle models.
