I was quite satisfied with my i-Circle case for the first couple of months: light weight, very little extra bulk added to the iPad, and the stand / grip was incredibly useful ... exactly what I had been looking for.
What changed my mind about it?... when my iPad feel from a low coffee table (just a bit over 1' high - had it setting flat on the coffee table charging, my dog got tangled in the cable pulling the iPad off and onto the floor). The i-Circle was worthless in protecting my iPad from even such a low fall - the corner of the i-Circle shattered on impact resulting in a small dent in that corner of the iPad. Besides not protecting my iPad, the broken corner piece left very sharp edges.
I have since found the same functionality and much better protection in the Speck HandyShell
Speck Products HandyShell for New iPad 3 and iPad 4 - Black/Dark Grey SPK1207I am quite certain that had I had the Speck HandyShell on my iPad when it fell from the coffee table it would have been a non-event... no damage to either the case or the iPad.
So, the i-Circle is a great idea... but, not that great at protecting your iPad from even short drops.
