Query: Not recommended

Being advertised as heavy duty for work pants, I assumed this item would be great. Unfortunately, this is NOT the case. The gap is too wide for most belt thicknesses, but I wear a much thicker belt which holds my tool pouch, and the back strap still occasionally comes unfastened. Not only will it not stay on my belt, the adjustment on the front straps will NOT stay in position. It is just the "friction" type and a person should be able to clamp this in position to remain as adjusted for comfort. I might try to heat the fasteners as I have read others doing, but I think the manufacture should correct these faults
