Hi Roel,
I have never used it on a gig but even just in my house it has been knocked a few times. Even so, its life span is far less than any el-cheapo USB stick I have ever known. They should make a metal casing for it or something because its a device you are going to be GREATLY relying upon for at least ten years. Maybe they make it cheap so that it does break, and they KNOW you are going to have to buy a replacement otherwise you can’t use your software !!
