First: all the people in the videos are skinny. Their belts don't need to be tight. Some of us have a belly. Some also have no butt. That's me. One video shows how to make the belt tighter but I simply cannot make that work. Hand strength? Old? (I'm 81 - but functioning damn well, thank you very much.) Anyway, I cannot get the belt tight enough to do its job. It seems to me I spend an inordinate amount of time buying and trying belts - the only ones that will in fact tighten enough for me are the ones with holes and they eventually wear out, look bad, etc. And in case you're wondering, my waist varies between 36 and 38, occasionally 34 (not often enough anymore, alas). As mentioned I have no butt so my trousers are constantly slipping down further and further. Suspenders have saved me much anguish but a belt would be better. Second: call the customer service line? Good luck getting a human. "Our hours are blah blah (and you're calling in that time frame). "Please send an email" --- NO, I want to speak to a human being! I've called at least 3 - and I think it's 4 times. Never a human. I have received the return email but in all my messages I've said, "I want to speak to a human" --- never happened.
