Yes, I purchased a refurbished Nook, never again, it was through Walmart.
It constantly, when it starts, jumps out of a book back to the home scene as if someone touched that button. I didn’t noticed it until about two weeks after buying it, of course getting the seller to respond was impossible.
It lost most of my ebooks. once, had a about 300, ended up with 35. I’m not sure if an update might have caused that, but the jumping out of the book makes the thing useless.
i may try to open the Nook to check it out, but I think it’s $35.00 blown to the wind.
