Q: The concept is great and there are some nice games on it but when I got the device, it froze with a black screen and then rebooted saying I had to install an update. I tried repeatedly until I gave up. They should work more diligently in fixing the bugs. This thing really needs work. Very frustrating for my kids.
A:
Bad review
