Purchased this while another exact model was sent in for warranty work. Wouldn't work straight out of the box. Sent it back immediately and ordered another brand.  As I a have another with an issue, I will say DO NOT BUY.Over time,, there is an issue with one of the ribbon cable becoming disconnecting, internally, which will not allow you to charge the unit. This was the issue with the one I sent in for warranty work. After reading about it, this is comment with this unit.
