I bought this to replace an old kindle. I thought it would be nice to have a reader and be able to check my email etc. I am incredibly disappointed. It is useless unless you can charge it every half day which defeats the purpose. I only get a couple of hours of use with a full charge, and have recently purchased a couple of books for the beach since it doesn't have enough power to rely on. It seems I'm not alone in this because lots of people seem to get a lemon like mine. It is also difficult to read outside on a sunny day...
