Premium Shockproof TPU Case for Amazon Kindle Fire HDX 8.9 (2013-2014 Model) - Slim Soft Protective Cover with Anti-Slip Grip | Perfect for Reading, Traveling and Daily Commute

I thought this would be a replacement case for my Kindle Fire HDX 8.9 but it is only one-sided (meaning it only protects the back side of the Kindle, not the screen on the front side). I'm not sure what the purpose of this 'case' is (and I use that word lightly) because it offers no protection should the Kindle be dropped.
