Purchased this to replace the one my husband was using where the strap literally wore through and broke.  Seems to have a much sturdier lock scenario than his last strap.  Previous strap was purchased in a shop at an airport but most of those shops no longer carry them for some unexplained reason.  Only time will determine IF this product will last longer than the previous one . .  I suspect the TSA will be the BIG determining factor there!!
