I bought one of these
as a temporary measure until I find a case I really like.
The spine part of the cover isn't quite as deep as it should be (the Kindle is a little flatter than the Glo), but it still fastens okay. I can fold the front cover behind the reader, and fasten it in place with the closure tab. The magnet doesn't affect the sleep/wake mechanism.
Despite the pictures on the website, the interior of mine is grey, not brown.
The silicone pad does hold the Glo in place nicely and it hasn't slipped yet.
