First impression: It's a toy. Impossible to work. Well it was a scam. It may be lightweight (which is a plus) and has the smaller cleaning pad I'm used to, but it vapes great with less effort. Very happy with it. It doesn't stand to use distilled water, which I already do, so I'm hoping it doesn't clog up with minerals. Now for the improvements: 1) a switch would have been nice and 2) a bigger water tank as I had to refill it quite often. (one star for that)
