I send it but on the same day back, because:
1. It works on my Windows 8 PC not, neither Office 2013 nor with Adobe Reader, although the manual promises. Among my other PC (goes Win7 but sees no problems - just plug and play)
2. If the processing really bad and the smell at least unpleasant. The hands still stink hours later for something where I want to know not at all what it is.
3. the laser pointer button is locked after play around 3 minutes - something must not happen!
I am looking for a better device, I suggest you also to look any further!
