I have the reader for my daughter brought since it reads a lot. I did not want to depend on Kindle me. The first reader who came, unfortunately, was not right. He flickered very strong, allied himself with the poor WiFi, and if he did it once, it was difficult to land in the shop. After 2 months, he forgot even the password. So return was announced. I was not sure if that would work fine to me. But contrary to expectations, everything went very well. Mir, the purchase price including shipping costs has been reimbursed, plus the submitted by me return package fees, and fast. That's what I call service. I bought again in the same company a reader, and works perfectly. Device super, excellent company. What more do you want?
