This shell has firstly a very nice color (bright red) and also does not feel so much like silicone on, rather for something softer plastic. The buttons can be still good use, not feature positive but insufficient.
On my Galaxy S3 LTE the shell sits very tight and you have to watch you lose weight, do not take the cover of the phone. This causes not so much dirt and dust between the casing and mobile phone passes, which can be but unfortunately not be completely avoided (at least in his pockets-operation).
Overall, a very visually appealing and practical cover for less money!
