Given an Amazon review, indicate whether it is a 'Positive Review' or 'Negative Review'.

Example Input: It work when is plugged in but then after minutes it will show Not Supported Error in IPad. I don't think this device is test/certified to work with Apple devices and manufacturer (and Amazon) should make a clear statement in the product description. I was relying on this to download my pictures and videos from my GoPro camera into my IPad and it didnt work! Try it serveral times even restart my IPad and same problem.
Example Output: Negative Review

Example Input: This is the worst pile of trash ever created! DONT WASTE YOUR MONEY! Buy books. Nothing about this works. After talking many times (for sevaral long periods of time) to Kendle \"customer service reps\", it is obvious that the service reps have NO clue about this device - especially how to troubleshoot or how to fix things. They have NO idea how to help. Total TRASH and waste of time and money.
Example Output: Negative Review

Example Input: This case is very functional, having the pivot arm on the back of the iPad portion allows you to position it easily and the fact that it the arm extends out from the keyboard base, gives you lots of viewing angles in both portrait and landscape positions. The keyboard has a really good feel too it and all the keys are in the right places. The power, caps lock, charge light and bluetooth connection switch are all easy to see located on the top of the keyboard just to the right of center. The back portion that holds your iPad in place seems a bit flimsy at first, but it is very well engineered and it holds and protects the iPad very well. all the notches and cutouts are in the right places. Yes, adds some bulk, but the overall functionality is really good it is light weight compared to others i have used.
