My first thoughts is why isn't this offered in the US? I had previously purchased several various gadgets that were supposed to be viable cases for an iPhone on a motorcycle. They were mostly junk with glaring design flaws, fragile and basically useless. They either would not hold the phone securely, flopped around loosely on the handlebar bracket or required hours of additional modification to come close to working.
I searched the web far and wide until I saw this offered and decided to give it a try. At long last! This thing works. Its waterproof, sturdy, the case is not likely to come loose from the handlebar bracket and even if it did you have a lanyard that can be used to connect the case to the handlebar.
5 stars all the way!
