Falls off so easily

I loved this bracelet the second I put it on. One of the larger clasps comes off to make it slightly shorter, which was better for my Sony wrists (although still a little big). Unfortunately, the clasp is not strong at all. The link clips into the largest link, and seems like it would be pretty difficult to fall off on its own. Within less than an hour it has slipped off my wrist and I don’t even think I was putting any pressure on the link. But I ignored it. It happened every so often if I was leaning on it or put my hand in my pocket, but I was able to notice it each time and I just tried to be more careful, even though I was still confused as to how it was coming off. Sadly, I was out last weekend and it must have fallen off when I wasn’t paying attention (which I really shouldn’t have had to) and now it’s gone. It’s such a pretty and unique bracelet but clearly cheap and very poorly made.
