After reading the reviews I thought I had found some decent quality slides. I ordered a pack of 10 pairs. 4 pairs installed, all failed. Drawers didn't quite move. And yes, they installed correctly. After they were all disassembled and examined, it turned out that the plastic that was supposed to stick to the soft part of the thruster didn't stick to it. It gets stuck quite a bit and you either have to force it in and break it, or just leave the drawer open. 4 more installed, same problem. These tracks are rubbish. I don't know if this is a common problem with soft close drawer slides. Went to Lowe and got the regular drawer slides and they work with no problems.
