I've got one.....and like it for the most part. A couple of issues. First, each time that you fill it, 2 things. 1. Be careful when you spin out the bottom airflow controller when you go to fill it....When doing so, the top part that connects to the air tube, tends to loosen up as you are loosening the bottom (watch because what's left of your juice can/will start leaking out the top as you are refilling it while it's in the upside down position). and 2. Make sure that on each fill-up, that you wipe off the inner part of the glass (where the white silicone like stopper meets with the glass), and wipe the silicone stopper off too. If you don't, it feels like it "welds" itself to the glass, and become a P.I.T.A. to get off, for the next time that you need to refill it. That's about it. Vapes REALLY well (IMO). Oh...one more thing. Be careful NOT to drop it......Mine DIDN'T like the wood floor from about a 2.5 ft drop. I picked up a couple of vapebands to put around the glass, in case I decide to drop it again....
......Hope y'all have a decent day!
