Decent rails. Just be careful if you remove the carriages and put them back on.

Smooth. The ones I got are smooth. However, there were some issues, once I took the carriages off for installation and tried to re-insert them back onto the rails. The ball bearings popped out like mustard seeds in whole grain mustard. The retaining wire is. sufficient, so long as the carriage is on the rail. I noticed that there were gaps in the ball bearings, so these carriages probably weren't filled to the max.Having said that, they work well. Good price for a decent product, just not a top notch product. Need to handle with care or be prepared to buy some extra ball bearings to refill in case of bearing losses.

Pros

The carriage block's stainless steel design offers excellent thermal resistance

Cons

The linear rail guide may be too short for some people, limiting their ability to work on larger projects

Rails are warped and the bearings are very sticky after hours of cleaning. I don''t know if they still use cosmoline but it is still showing up in my mineral oil after about 5 hours of cleaning and 50 hours of low speed cycling.
