The shipping took forever in relation to my present other orders! The buckle seems to work well, but even the length adjustment would have to be blocked when the belt is attached to the trunk!
With a week (7 days) Shipping time the suitcase belts arrived too late and were no longer needed. That something like that in the age of Internet and direct debiting still exists. At least the suitcases were there two days later. Simply annoying !!
