Good fitment
Slightly tight at first but loosened up after some use. Quality seems solid for the price point.

Great for CNC Router
Smooth motion on my X-axis. The wide opening made installation much easier than standard blocks.

Excellent quality
Better than expected for the price. No play in the bearings and they glide smoothly on hardened shafts.
