Ok it has to be said super fast shipping and this makes the 4th atty I have ordered from them with 2 more sitting here new (have not tried them yet) but it makes the 4th atty that I have received now that I open the atty from the plastic screw it into my 901 fill a new cart with Vanilla from where Esmokey treats of course then I puff away and guess what there is no bad taste not even the first puff. I cannot say that about the attys I have ordered from anywhere else. No where!!!! I used to be scared to inhale on the first puff but not these. Oh and the round tips are awesome!!!!!!
