Beware that if your kindle goes bad after the warranty period of 1 year (which is very unlikely), you will have to discard it. it is a use and throw product.There are no repair centres in the whole world wide for kindle. Once it goes bad you will have to discard it. So think twice before you buy your kindle- a non reparable product. My kindle screen became frozen and unresponsive because I did not use it for about a month and it is now irreparable. I would say that Amazon should clearly mention about this in the product description and make the customer aware about it that it is an IRREPARABLE PRODUCT. This is like cheating your customer without making them aware of what is waiting ahead. Secondly, don't just sell, set up repair centres. If you have invented this product, you should also know how to repair them.
