I take my Kindle everywhere and have been using the official lighted cover from Amazon for some time, but I have never needed to use the light and I found the bulk and weight added to my Kindle unappealing (it makes the device twice as big and twice as heavy, at almost half a kilo). With the added high price tag of the lighted cover, I feel like it was a waste of money.
I much prefer the feel of the Kindle without any case, so just wanted to get a slip on cover to protect it while in my bag, and the Shocksock case does the job perfectly. As others have mentioned it is not Neoprene, which I think is a good thing as I don't like the smell of it. This case is more of a padded foam, which will do the job of protecting the device from knocks and bumps without any problem. It fits like a glove, is very well made, and only costs £5 delivered! What are you waiting for? go buy one, you won't regret it!
