Review on 👖 Invisible Stretch Belt for Jeans/Pants by Bugle with Bonus Interlocking Buckle by Shay Johnson

I bought 4 of these belts, 2 dark blue, 1 black and 1 brown. I love the concept of these belts. You don't have to unbuckle to use the toilet and they fit snugly. However, I have a problem with one of the blue belts. There is a snap button to adjust the size. This one doesn't seem to fit. It always comes undone and the next thing I know my pants are coming down. I've tried snapping it in several times and it won't stay on. Definitely a defect in the adjustment clip. I don't know if I would buy again. Very frustrating
