The device itself is qute and looks ergonomic in principle. I say in principle because I could not get it to work. I tried it on a windows laptop, a windows desktop and an android phone. I followed the instructions but the thing was missbehaving in a different way in each computer. It was doing a different thing every time, but the bottom line was that it didn't work. I sent an email to their customer support and I never got a response. It's now sitting on my desk for two months, I should have returned it really. The only reason I gave it a second star is because of it's potential once it starts working (hope dies last!).
