I have it installed on my 7 inch Kindle Fire and it works well. I wouldn't be without it. It's an awesome cover that I can't say enough about! I've had other covers before but they all left some bubbles or streaks or waves or something that this Moshi doesn't do. I love the fact I can wash it and re-use it over and over again too! Moshi ROCKS!
Sir, this item is manufactured for the Kindle tablet. I purchased it for my Kindle and it works great for my tablet, however I cant answer if it would fit another brand of tablet because every tablet has its own design and size.
My Kindle Fire is 7" and the screen I have on it is 7" and it works very well. I have not had any problems with bubbles. You can take this one off and clean and put it back on. My granddaughter has one also and she doesn't have any problems either. I don't know why it would not work for you.
