Review: great packing thank you - packaged good. real good lol. box was a bit banged up from the mail people. but the rails where protected inside the box thank god. they or great rails i am very happy. thank you. would buy again.
Review: You pay for what you get. - They are noisy and you can fill the balls as they contact the rod. The first two treads are good, the rest, you will have to pick up a tap M5-0.8. These act like they are metal powder formed when I tapped these.

### ⭐⭐ You pay for what you get.
*by R***T on February 28, 2026*

They are noisy and you can fill the balls as they contact the rod. The first two treads are good, the rest, you will have to pick up a tap M5-0.8. These act like they are metal powder formed when I tapped these.

### ⭐⭐⭐⭐⭐ These simply worked for my application.
*by P***. on December 15, 2024*

The glides run true and can be adjusted for how tight they are on the rails. They worked great on my custom built piston ring file.
