I am not saying this should be done on a regular basis, it's just a test, primarily for Amazon staff to verify the reports, and as a company that want's to serve it's customers fix the problem. Either stop selling the cases, recall the ones sold, change the design of the Kindle and recall the old ones or something.
But right now the situation is such that some people return their cases with the refund, some get a refund without returning (hard for me, I am from Croatia), or some are offered an upgrade to the lighted cover.
Also if you have a device that freezes often, due to static discharge, than one more will not change the game, esp. for those covered by warranty!
Hope we have a solution to the problem soon, and that this will help people stop speculating what's causing the problem, as some still think it's the winter. It is, but not because of the temperature, but the kind of clothes we wear
Hope this helps!
