I have had 2 off name brands of ereaders, I would advise everyone do NOT buy any e-readers or tablets that is not from one of the main sellers. I intentioally bought the cheapest I could find last year at Christmas (which was more that they are now), just to see if I would use an ereader. That one lasted maybe 3-4 months. My replacement one, a different brand BTW, hasnt lasted 2 months. And I am not that hard on them.
Dont be tempted by the BF sales on the off-brand sales. If you research the brands you will find that a lot of paople were unhappy with them. JMO
