The strap and the plate initially seem good but the design and construction of the plate prevent the screw of solid and stable manner to the housing. After a few days, you have to regularly tighten the screw, which eventually split completely the plate and become unusable. It only remains to find a metal buckle to fix the housing to continue using the strap without the broken plate.
This is not an isolated defect, it happened on 2 products mounted on 2 different boxes.
