It has a 3 year warranty.

The cost is high, but I'm smoking like $200-300 of pot every month. This thing effectively halves your consumption, solely because it takes less to get just as high.

I also like the convenience of kinda "set it and forget it". I can wake up, get it running, and get up and get food and shit, come back to a bag of vapor. I also like how party friendly it is, and how it's not fucking up my lungs.
