Material and feel are very good, but the fit is more than poor. The edges of which draw on the long sides hardly around the unit, but hanging out with a good 2 mm spacing above around. There seems to be lacking either just on the shell back material, or the beads that are to engage around the edge are, insufficient capacity or too soft. I had silicone cases for a Galaxy Tab 10.1, which were better despite the size. Also for my grade 2 and Xperia Tipo my fit the envelopes perfectly.
This case here, I can not recommend.
Update 6.1.13: My sleeve must be well broken; a replacement cover fits better, but still not perfect.
