I have the same problems with my 801. It sucks .... Burnt taste and not much vapor. The attys only last a couple of hours, but I figured it was because I was vaping too much. I'm thinking of getting a 510. The first 2 days of using the 801 was ok, it was the first ecig I bought and I was off analogs immediately, but untill I can get this thing working right, I'm gonna have to use a few analogs. UGH!!! I'm gonna try some of the tips listed here and hope for the best. Thanks guys.
