I know I'm getting ripped off at $21 for the case, but I couldn't find anything cheaper that looked like it was as protective as this case. This case feels like the heat resistant silicone that one would find in kitchen utensils (oven mit, basting brushes, etc.) Intended for an ASUS product, so there is no doubt that the combo will last a very good while (in the hands of children - ages 4 & 5).
Pros: The case completely covers the MicroSD card slot keeping out dust and possibly liquids, A+ on the shock absorption build.
Cons: Price, and the case should cover more of the forehead and chin on the tablet (but not a deal breaker).
Not sure if it's a pro or a con: The speaker for the MEMO is on the bottom rear, the speaker opening on the cover resides in the front. Well if one carefully examines the this, the case provides a sound tunneling system to redirect the sound to the front. The pro on this feature is that the tablet is less vulnerable to damage from liquid spills on say a table. The Con: sound suppression??
