Query: Stitching came undone within first hour

The stitching holding the hard plastic front pieces onto the pads came out in less than an hour of use. The tops of the hard plastic front blue piece on both pads were completely separated from the pads within an hour. The cheap construction alone is why they get 1 star. I never liked hard plastic caps on knee pads I thought the gel-filled was referring to the front of the pads. The hard plastic fronts slids to easily on plastic lumber when decking ramps.
