As I understand it hannspree is the low end of hansgee. Hansgee being low end itself. They generally have decent prices and ok reviews. But my friend who runs the tech department for a company had a bad experience with them. So I avoid them.
if it's working, looks ok, and it's a good deal/trade id say go for it.
I have a 23" Hannspree monitor that is still working well after two years. No dead pixels. Speakers sound just like they did when new... horrible. The non-glare coating causes colors to appear washed-out. But for the price it was a fair deal. However, for $40 more my ASUS 24" monitor makes the Hanspree look like junk.
