Okay my first E-cig was the 510 I have had this for over a month now. I blow threw the Attys to clean them out every once and a while and they work great. I purchased a 901 and it was working well. I Blow threw the atty to clean it out I prime it and now it just doesnt work. I thought maybe it was just a bad Atty luckily I had a spare. A week or so go by I clean out the new Atty it dies to. I managed to some how revive one a little bit but it doesnt seem to be working all the way. I am only able to get a little vapor out of the one. Oh its an auto battery to. I guess I just need to be a little bit more easy on the 901 attys. Anyone else have this problem or know how to bring the life back into them?
