Agreed. I'm surprised not a single reviewer has made any comments about spitback, though. Similar issues with the Cubis tank were also never adressed by reviewers.That's a pretty good review, a lot of great info for newbies in particular imo.
I hope he's wrong about the 18650 though, can't stand them personally. I think I'll hold off until someone opens one up.
And what's wrong with an integrated 18650? Would it function differently than an integrated LiPo battery?
