Query: Horrible Product!!!

This has been the biggest disappointment imaginable. What a terrible experience. I called Amazon when I had difficulties with my 1st Kindle. Amazon sent me a "replacement" Kindle. That was nice. It would have been nicer if it would have actually worked properly. I have had the same issues with the second Kindle that I did with the first one. These are both the same (original Kindle) models. Perhaps the later models have improved. I will not be taking that chance.
