i've had mine for prolly about a week now, and i love it....everyone who tries it loves it...the hits are just as potent as smoking (if not more), it saves a shitload of weed, the high is nice and long lasting, my it could be all in my head but my lungs feel better already. We used it in the bathroom at my friends work with customers walking around, and you couldnt smell a thing. I've seen more then a few everyday smokers get put on their ass by this thing. Check this site out, they break down the features of most vapes out there. I chose the Silver Surfer Vaporizer (SSV), and I'm completley satisfied. $145 on ebay, super fast shipping too.
