I purchased this product about two months after acquiring the Kindle, and I chose this product based on the recommendations of others. Well, perhaps it works with a brand new Kindle, but I found it disappointing. Perhaps it is impossible to get the surface 100% clean once you used it. Also, the instructions suggest applying it in a dust-free environment, which I just don't have. What ever the reason, I ended up with several large air bubbles on the surface. Reapplying the product made it worse. I ended up tossing it. However, I would like to commend the company for trying hard to satisfy their customers. They reached out to me repeatedly and offered to send me a replacement free of charge. In the end, I declined because I didn't think it would work. I didn't want to waste their money and my time, but who knows - it might have worked the second time around if I had tried it.
