another website reported alot of problems
A lot of problems? I dunno about a lot of problems. Nobody but the company knows how many they've sold vs. how many warranty claims they've had. But I haven't seen a lot of posters saying theirs crapped out. One guy has been relentlessly engaged in a vendetta against the company (on multiple forums) because his had a problem, he opened it up and operated on it, and they voided his warranty because he took it apart.

I've had one since they came out last Oct. and like it a lot. I use it probably 4-5 days a week for portable use. Since it's a new product it'll take time to evaluate long term reliability. They do offer a 2 yr. warranty, which is pretty good for a hand held, lightweight vape like this. The company also has about 25 yrs. experience producing gas powered tools, which has to be a plus. If you're really hot to get a stealth portable, I'd say go for it. It does a great job. If you're worried, wait and see. They do intend to introduce more models. You can also get some info straight from a company rep here- Fuck Combustion - Vaporizer Forum / I-inhale vaporiser . If you decide to buy, the best deals are from UK sellers on eBay. They're selling for as little as $150 delivered to the US. Even better prices if you're in the UK.
