There's a lot in this thread about future suggestions, which seems to me to cut it's signal to noise ratio, there's a whole forum here full of future suggestions, whereas the OP needs to get through more basic hurdles first. She's also spent a lot already. Wasn't trying to be harsh, maybe should have put (j/k) after my comment.
As to the Provari 2.5 itself, in the long term maybe one would be good for me, but if I decide that it will be a result of trying a more power etc. with more flexible units myself and deciding I can work within its limitations and enjoy its advantages. I'm not impressed with the difficulty of finding specs on their website, seems too much "trust us, we're the best".
The "Gotta be better than being palmed off with a load of crap all the time" line seems typical of Provari fans and is inaccurate.
There also seems to be a sort of battery fetish on this board: Having problems with the topper, get a better battery

.... While battery units have displays and fancy stuff, I consider the atomizer side more interesting, and your needs there determine everything else.
