A quick www search will tell you what users think of this product. It does the job, but the water tank is definitely going to break with routine use. The design is ̢���planned obsolescence̢���� at its finest. Also the 1x1.5 inch touch screen is not user friendly. It̢���s too small to see at night, and it̢���s VERY hard to use. It̢���s small size and poor touch screen result in 3 to 5 presses to get it to respond. A larger, more responsive screen on the side (rather than the top) would be easier to see when laying down. This screen requires you to sit up, put on glasses, and poke it repeatedly to use.
The Bluetooth application is also less than useful. It is slow to connect, and doesn̢���t offer more info than the tiny watch-sized display panel.
I̢���d like to see a greater degree of flex settings as well.
On the positive side, it is small, and quite. The tubing is long enough. I can̢���t comment on the heater since I don̢���t have that option.
