How is the Vapir oxygen mini?

The reviews seem to be pretty mixed, what do you guys think of it for a portable vaporizer in the $100 price range?

It works great but is made very crappy. The portable battery pack doesn't last more than 4 sessions. The only time I used the batt pack was on my boat so I hooked up a female car adapter to a marine battery and it works forever. The connector is similar to a phone jack. The wires have come loose on my home adapter and ive only had it for 2 months. It still works but if I bump it the wrong way it shuts off and resets the temp (if that happens in the middle of vaping it sucks real bad, you have to turn the heater back on real quick and get the temp back up) It could definately be made better but keep in mind I use it ALOT. For a casual vaper it should hold up for a while (at least enough to get your $100-$150 worth. Im shopping for an iolite now I do prefer the hit of a fanless vaporizer over the vapor bags tho. My vapir oxygen seems to be more efficient than my vapir one, which also is kind of starting to crap out after 4 months or so, it still works but the sounds of the fan tell me its on its way out
