The Case-Mate mobile phone Protective Case for Samsung i-9000 holds up to now what it promises. Have you only just 4 weeks. The shell feels through these "rubber" effect is good, and is very slippery. Despite these rubber elements it is still stable. (Have you ever fallen off nothing happens. No scratch) Unlike pure silicone sleeves (the tear easily a) this is actually my feeling after optimal. It fits like a second skin on the smartphone. It has all the necessary openings (charging cable jack, headphone jack, volume up / down rocker, camera lens ...) in the right places. This casing also makes the phone not unnecessarily thick but nestles itself. All in all, finally a successful symbiosis between functional protection and tasteful look!
