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.
