The metal on these traps are pretty cheap and bends. I had bought some others from a different merchant in the past that were great, the metal held up very well, I was thinking these were the same. Clearly they are not. I used a set of the straps one time and was being stabbed by the metal because it bent, lucky for me it didn't break off, how embarrassing that would have been to loose my strap mid day at work etc...!
