Kindle - Demo Unit ONLY
I have a friend who got a large quantity of Kindle and Kindle Fire units. On almost all of them it has the words: Demo Unit Only - Not for Sale
I am looking to purchase a Kindle for me and Kindle Fire for my wife. If I purchase one of these unit can I use them like I could a unit w/o the "Demo" part on it or must I get one w/o the "Demo" part on it to use it?
I am sorry if this has been asked before - if it has a link to the answer will suffice. Thanks to all for any help you may be on this issue.
