Query: DONT BUY!!

[It] broke, not just ceased working, it broke. As I pulled it out for the first time a little piece of the microchip stayed in the system, which i then had to pay to get it removed. We returned it and got a new one, SAME THING HAPPENED. This time i just used a screwdriver to get it out and I returned it for a refund. DONT BUY!
