The clear TPU case I purchased off of eBay arrived yesterday and I've had it on for a day.
Pros:
Minimal additional thickness.
Doesn't distract from stock appearance of reader
Provides insulation from the cold aluminum body.
Cons:
Not much protection for the front.
A little difficult to put on and take off.
Makes it a little difficult to access power switch.
Notes:
The top and bottom accessory cover holes are covered by the case.
The swirly circle design on the backside of the case are etched on the inner side.
Overall I think it's a good minimalist case and I think it would pair well with decal skins to provide a little more protection.
