I bought this unit as a gift for the grandchildren to read books. My plan was test it out and buy 3 if it worked. I planned to buy gift cards for the unit so the kids could buy books. Barnes and Noble requires a credit card to activate this unit! That is a show stopper as it is not desirable for young children to have a unit with credit card information linked to it. They could lose the unit etc. I loaded my credit card information to test the unit. After deciding to return the unit I talked to customer service about deleting my account information. The answer from 3 people was you can not delete your account information. I can not recommend this company.
