I too love the little 'lunch' box, so portable, discreet. But as vapes go it is a little underpowered, I also worry about how durable it will be in the long run. It has a small small heating element (kinda required, 1 AA battery operated). One of the things about it that is good is that it is nearly impossible to actually light up and burn the herb instead of just vapin it. SS is a good one, some knock offs are very good too, just remember that vaping at lower temps is easier on your throat and lungs. Also the experiance helped me understand that I don't really want to turn any herb into ash, you got the good stuff before it turns black.
