Good value

Overall satisfied with the quality. One bearing was tight initially but loosened up after some use. Good price point.

Great for CNC build

Shafts are straight and smooth. The aluminum supports made mounting very easy. Highly recommend for hobbyist CNC projects.

Okay quality

The rails work fine but the packaging could be better to prevent minor scratches during shipping. Functionality is not affected.
