Well I just got mine and here's a quick impression.
The unit feels well made except for the mouthpiece. Solid rubber/plastic body and an aluminum bottom plate. The unit is sturdy, the button doesn't feel flimsy and the magnetic top and LED is awesome and easy to use.The bowl is also easy to fill with much less waste.
I did a dry run with it and it did have a plastic smell initially, nothing too bad though. Closing the pathway on the bottom really means that you cannot suck through the mouthpiece anymore. Have tested 3 settings (2nd, 3rd and 4th) and well, it's intense. On the 2nd setting (Blue 180C) you feel the vapor through your throat but there is absolutely no vapor when you try to blow out. This however doesn't mean it doesn't work. I was pretty baked at the end of the session. Compared to the flowermate there is almost no vapor. ABV is very evenly vaped even in the middle. I didn't have to pack the chamber like the flowermate either so I guess there's convection going on. It's also considerably lighter than a FM. I'll post some comparison shots up later.
The only thing I don't like is the plastic mouthpiece. It's not ergonomically shaped and doesn't give the best taste, but it still works pretty well. You have to have slow sips because otherwise the chamber can't keep up, it's not much different in rapid mode.
