Not impressed. Battery failed to charge after two weeks. Got an authorization to send it to Asus, and when they sent it back, "repaired", it would not turn on. Shipped it back to Amazon for a full refund. Since then I've seen this puppy for $299 on Groupon. Don't waste your time or money. The upside is the ASUS employee I spoke to was very courteous, and sounded Amaerican. Unfortunately they can neither make, nor repair a tablet computer.

I tried this but it had a sticker on it that would not come off easily. When it did come off, it left a large translucent smear in the upper right hand part of the Kindle getting in the way of the controls in that corner as well as making it difficult to read. I tried two of them, both had the same issue. I would recommend getting a case for it, does a better job at protecting the device and does not get in the way.
