none, except that its small

Well the manual tells you nothing and makes absolutly no sense at all. The images are soooooooo grainy. I can't even believe i bought this and now i am going to send it back to the site it came from. What a waste of money

Not many

The video quality is poor, the manual is...what manual? It doesn't tell you much. It was obviously written in Chinese and translated with a software program. The remote is very fickle and PIP changes the video quality to purple. You have to restart the PC

not many, The device does just not work as it is supposed to no matter how much you mess around with all the options in the menu

Video in general is poor, always had a static bar at the top of screen and entire video just looked kinda grainy on high resolutions ; when switching to PIP and going back to full screen the whole video becomes polarized ; You can't actually change...
