So I sold a 901 set to my friend 4 months ago. Well today he came back asking me why the cart wont stay on anymore - I took it off and looked inside and saw that there was NO liquid or even the polyester (?) in the cart and that the atomizer had dilated so that it wouldnt hold the cart. He told me he never added liquid to the cart and had been smoking it dry for the hell of it. I only gave him 5 carts from 4 months ago.... I don't know how he could have smoked it for so long and tolerate the taste - but what's even weirder is that it still produced vapor with nothing in it and that it still produces great vapor when I put a fresh cart in after 4 months (he never came back to me for a replacement atomizer and his batteries still work like new!) with him smoking it dry for so long- how is this possible?!
Or is the 901 really that great lol.
