It's a great part and the only negative things (both are behebar):
1) The quality of the film is controlled by the S3 is insufficient. The operation runs without problems, only is this film so sensitive that they had several scratches after only the first use! So just gently wipe a mud splash is not at all - must be rinsed with water. What have I done about it (PLEASE BEFORE USING NOTE): Just on! the film of Rain Case still stick a normal S3 Screen Protector (the compact)! Believe it or not, but the operation is then still no problems and the Rain Case foil is protected !!
2) The handlebar mount while sitting very firmly and is well adjusted, but for my taste it has fallen very large, so the S3 is very far away from the handlebar and even protrudes quite a bit! If it sometimes throws a the wheel, you will first depend on the S3. But for this "problem" there are home improvement a solution: I have the support adapted (about 3/4 of it ground away) that I save space in the handlebar stem mounting tube (embarrassing - reminds me of the name just does not could integrate a ...). I try later times to upload a picture of it! Daduchus the S3 is now not so far and is also less sensitive to shocks. With this modified bracket I'm neat downhill slopes down and the phone has kept perfect!
As mentioned at the beginning: Everything else as water resistance, stability (to the film), design ... are super!
In summary, I highly recommend the Rain Case with an additional screen protector!
