So BOBJ deserves a star for the simple fact of existing.
Otherwise, it is correct, the rubber is dense, a little dust catcher (black model), but in return, the tablet becomes much less slippery. Large strands around the frame are not necessarily very aesthetic, but it was "almost" urge to drop to test the effectiveness of thing.
As negative points, it is not really given, and in view of its price, one would expect a somewhat less rudimentary appearance (it's still technical rubber) and a better fit: I have a slight game the upper edge. Result: the volume buttons (the only ones that are covered by the case) are much less accessible, and well if I try to replace this bracket, back bends a little. I do not know if it is clear ...
In the end, everything is in the title: I have not found other models for this type of protection, so okay.
