Smooth and Quiet
The media could not be loaded. These were smooth and easy. I used these for modifying my Y axis on my Taz6 as I hated the igus bearings.

Works great for Ender 3 S1 Plus Z axis!
Picked up a pair of these to upgrade my Ender 3 S1 Plus Z axis and get rid of the pom wheels. Rail was straight, carriage head ran nice and smooth!

The linear rails work well, they blocks are a little stiff, but over all good for robot projects
I added these rails to my robot, they work well, the blocks have a little friction, but great tolerances

Smooth and straight!
Used this to replace my x-axis on a custom large 3d printer. The original one somehow had some burrs and the bearing destroyed itself in a mistake. This replacement is super smooth and strong. Fit was perfect

Surprisingly nice rail
Got this to update my Voron to the R2 spec. Wasn't expecting the rail to be seemingly pre cleaned, and only generously coated in light oil. Moved like a dream, just enough preload to not just zip off into the distance by accident, but smooth as butter when moved without even a hint of play in the rail/carriage. I am quite please with this rail.

Bad tolerances
I purchased a single carriage &rail combo plus a double carriage & rail combo. They turned out really smooth. Then I decided to convert the single combo into a double by buying a single carriage to add. The first one came in way too tight, unusable. Exchanged it for another and the replacement was worse. Tolerances are not compliant. Seems like the manufacturer is sending out matched pairs so they don’t need to keep tight tolerances. Therefore, don’t buy single carriages to add but only buy matched pairs.

Worked Great
Used these to replace a worn out Hiwin block. Much cheaper and so far work great. Old Hiwin had about .5mm play, this currently has 0. Will update if bearing fails early but so far VERY GOOD inexpensive replacement with no wait time for overseas shipping. Delivered next day!!!! Thank You...

Very nice rail. Very smooth with no cleaning or oiling needed. Sealed in a bag.
I got this rail in a sealed bag and expected to have to open it, clean it and relube it. I was pleasantly surprised that it didn't need anything. (other than to be installed) I have never bought a linear rail that didn't need cleaning before. Not that it is hard to do but I just expected to have to. I will look for this brand for my next linear rail purchase.
