My Samsung S5230 fits in wonderfully and is now protected wonderfully on the back, as well as to the frame by silicone protection.
Recesses can be found at major ports such as the headset port on the side and the camera on the back. The three buttons on the front are also protected and displayed.
As already repeatedly addressed diesr article contains no screen protection. For this I recommend a screen protector.
The quality can be quite impressive and so you can make at this price in my opinion nothing wrong - excellent value for money.
