Review on CO Z Furniture Glides Sliders Protector by Josh Boii

I decided to purchase these glide pads based on the lower price and positive reviews compared to other similar products on Revain. I was originally going to give 4 stars because the sliding parts actually work, but deducted 1 star because many of them had very thin sliding surface material, to the point where they were translucent and you could see the black plastic underneath. The sliding material ensures that your furniture slides smoothly. As the slide material wears down over time, the black plastic underneath will leave black stains on the floor and the slide will no longer function. I would estimate that 1/2 of the gliders had less than the desired amount of glide material. Overall the slide works but not sure for how long.
