Attachment: You can attach well and protects the phone properly. For the front but a screen-film is to be considered.
To feel: This is average. The back is very smooth and looks a bit cheap. It is also prone to scratches. The pages are but rough, resulting in an incidence total provides a good grip.
For quality: Except for the susceptibility to scratches tidy. The cut-outs for all connections are good, everything important is well protected (except for the screen).
