Review on Ultimate Precision: MICRO JIG ZEROPLAY Miter Bar for Perfect Miter Cuts by Wesley Carreras

I installed them on my new slide and then adjusted them several times. While my sled was sliding normally, I found pieces of plastic in one of the channels on the table saw. On closer inspection I see that they have come loose from the bevel. Maybe I overtightened them, or maybe I was a little rough putting them up. I'm not sure if it's not my fault but I don't think I treated them very roughly so I doubt their durability. This is a great idea but I found them a little brittle and when one of them broke for me I just took them both off and went back to the wooden slides. I wouldn't go down this route again, I would either buy an aluminum or UHMW set or just cut some wooden skids.
