There are very thin shells (as the name suggests, ultrasilm), which remind me of thermoforming films. Find that it describes quite aptly.
They offer protection from scratches at the back and on the edge.
The mobile phone is not necessarily better in by hand or is less "slippery".
The cases close up flush with the display, ie it does not extend beyond and therefore do not provide protection if one puts the phone with the display on the table.
Probably you can use S3 Handytaschen additionally with these very thin cases, but what / silicone shells often does not go with thicker Cases.
+ The volume control and the lateral. Button are freely accessible.
+ The cutouts on the back are taken very closely with me.
+ The cases fall at my white S3 hardly, as I said very thin
- The cut-outs for small pendant top left are unnecessary, Case stands on the site something from (clearance) and dust may become embedded nice - you can hire but even simple seal
- Shocks will be able to intercept the case probably less
- Delivery: ordered on Sunday delivered on Friday
I currently use but another case, which gives me a little more protection, but it always comes on what is required of an envelope.
As scratch protection for Back Cover + 2 edge these cases are great and the price-performance ratio is good because you get 2 cases.
