I was a little afraid to buy a brand I did not know, but I'm very pleasantly surprised! I recommend this product, easy installation (not even 5 minutes), the sensitivity is really superb, the shorter are very good (rewind, zoom in / out, gum, etc ...). To install follow the manual (in English, but nothing complicated when the CD is launched the installation is in French). Please do not plug the tablet if the installation CD is not finished. I want to clarify that I am on Windows 8 and I had is no installation worries.
