I've had my 905 for a week or so now and here's my feedback FWIW.
So far, it hasn't heated up, caught on fire, or broken.
It pretty much does the job I expected, as I expected. Vapes just like a regular 901 bat in terms of output. I'd say it lasts about 6 hours or fairly heavy vaping. Actually the bat lasts longer but at that point the charge had declined to the point that the output declined as well. Was still functioning however. I have no problem with the buttons, the led, etc. but I'm not picky about that kind of thing.
Didn't really want a high volt experience either as I don't feel the need to choke on throat hit (But that's me...I'm happy to not be coughing from analogs anymore!).
It is heavy of course because of the bat. Which is why I'm not much of a mod freak. I like the lightness of a regular 901. I also like the auto bats; pushing buttons just isn't like smoking to me and after having quit for 6 months now, I still have that oral thing going on.
Especially for the price, I am finding this to be just what I needed (as long as it doesn't break next week!). I only really wanted it when I was going to be away from home for long periods and didn't want to hassle with taking a bunch of spare bats with me.
So that's my report!
