Review on 🛠️ Furniture Mounting Solution: Bearing Extension Section for Sturdy Installation by Rob Madden

They don't hold water and are poorly made. Installed for the first time, works perfectly. But shortly thereafter, they began to sag, weave back and forth, and were set perfectly even and level. They have a very thin piece of metal with holes covering the ball bearings. I noticed that the metal above was bent and the bearings in the track had come loose. Put them back in place and bend the metal again. I would NOT buy them again. Spend more money on a better product.
