Works fairly well.
Works pretty good so far. Not too hard to align. Fairly smooth.

Poor support
Product was fine, but I am missing the end alignment dowels which wasn’t a big deal because I am not in a rush. Reached out to the manufacturer for resolution with no response. When you purchase anything a big part of quality is support. That’s why they received one star.

Linear rails and bearings
Installed these rails on my concrete plasma machine and so far they work s long as you make sure that no debris get into the bearings.

works as advertised.
very hefty rails no bending under the weight of a plunge router and my weight reaching over the work piece. they a bit noisy and probably could use more grease but that would cause too much dust buildup. came with hardware screws and a stopper handle but still had to purchase more since they were to long for my application. as a side note i accidentally purchased the wrong size and were too short to complete the task but worked as advertised. very satisfied with this prodcut.

Great rails but with just a little bit of flex
Great rails but with just a little bit of flex. I used these for a router sled. There were two drawbacks. The first was hunting for the correct screw size of the holes on the mounting blocks. (Metric6 by the way) The second if a little bit of flex in the rails. For a full size router I may have to go back and add some steel underneath the rails so they don't sag.
