I own a Huion GT 190 which to be honest I wouldn't recommend. However, if you want you can view it here.
The problems I have with this drawing tablet are
* Not 100% accurate when you touch pen to screen (where cursor shows up).
* Material it's made of sometimes screeches when you are running pen along screens surface.
* You often need to restart the software as it will stop working.
* Found it hard to get a good position to draw, even with the ergonomic arm.
* Viewing angles and colors could be better.
* 720p seems like low resolution for Art to me
The Good Points About The Huion Tablet
* It is a lot more affordable then Wacom Tablets
* Speeds up work process in general.
