Good quality, slight shipping delay

The product quality is excellent and works well with my SBR20 blocks. Only giving 4 stars because shipping took a bit longer than expected.

Exactly what I needed

Bought these for a custom 3D printer build. The shafts are straight and the support blocks fit snugly. Highly recommend for DIY projects.

Solid construction

Heavy duty rails. Make sure to lubricate them before first use as they come with a protective coating. Overall very happy with the purchase.
