I have one on my S3 Nike that I use as an extra exercise and heavy chore watch. I have a Rhinoshield for my S5 SBTi as well for when I go hiking, etc.
It is larger than some other ones I have used but I feel it does a good job. I ordered via their website and got a free extra color bumper that you cannot get on Amazon (I ordered three for my two and another S5 Nike).
