I have had my vaporizer for 9 days or so and I love it! It is a nice device that saves me quite a bit of cannabis. I am using about 3/7 the amount I used before. I use a little less than half but more than 1/3 of when I smoke in a bong. The highs are a bit more clear headed which is great for right now as I am crammed with school work, but doesn't quite give me as much of that little mini-vacation feeling.

Value- I would buy this thing for $140 all over again. It doesn't look cheap and the parts are good quality. The logo is burned into the side of the wooden box and adds a nice touch.

Efficiency- Like I said before, I use less cannabis and get just as high. I feel safe saying that this vape uses half as much as my bong.

Effect- More of a clear high. I don't know if it is the stuff I am smoking, but it seems like when high I am more functional, I can get things done, and I can solve Rubik's cubes faster than when smoking via bong.

Overall- I would recommend this product. The only downside to it is that you have to let it cool down if you store it in a small area. I just don't want something at 350* Fahrenheit being so close to the fabric of a backpack (where I store it). Two minutes after being off is enough for it to cool down quite a bit. The smell is very low and smells like hay. I smoked up, put it away, then went into the bathroom when my mom came inside my room. Usually she can smell when I smoke outside from across the house when she is sleeping (no joke, got caught twice that way), but this time she walked in, and didn't notice a thing only 3-4 minutes after I vaped a bunch of cannabis.

Great product, I recommend very much.
