Bought this for a friends kid that was going back to school. It works great. Also you can save a few bucks by buying it recertified.

I get it was “refurbished” but it came dirty and grimey and within 2 days of having it, a whole row of buttons stopped working. Pretty PO’d about it. Especially for what it cost.
