Great quality for the price
Good quality, smooth motion, no slop or play and packaged like a tank.I’m going to buy more for my old delta and the y axis on an ender.

Good quality but sliders bind
Good quality rails but two of the sliders are super tight - binding heavily. I know it's the sliders because I have a third slider that works perfectly on all rails.

Good Value and quality
I recently installed the MGN12H 500mm Linear Rail on my LumenPnP X axis, and I am thoroughly impressed. The rail is incredibly sturdy and provides smooth, precise movement, which is essential for accurate positioning. The installation was straightforward, and the build quality is top-notch. I appreciate the attention to detail in the design, which minimizes any play or wobble. Overall, this linear rail has significantly improved the performance of my machine, making it a great investment for anyone looking to enhance their CNC , 3D printer or pick & place. Highly recommended!

Accurate and smooth
Good quality and smooth operation, one arrived a little scratched but seems superficial, no issues with friction or anything. Used on custom 3d printer, exactly as designed and runs really nicely with a little bit of grease.

Awful, bowed in every direction
The media could not be loaded. Complete waster of time, it's bowed by1.5mm in every direction. Do not buy!Would give 0 stars if I could.

Expect minor variance in quality
Bought 3 in total. First one was perfect after cleaning and lubrication - would've given a 5 star. The other two had minor binding and of those two, one was slightly bent (~0.5mm). Spent some time to minimise the bend during mounting but otherwise works well. All 3 arrived with the carriage on the rail, which may have caused/worsened the issues during storage and transport.

Not all items work as expected BUT.........
Seller was quickly to attend. Seller is responsive and sent replacement for the cartridges that rather sticking. Replacement are now much slidey-er. When service is on this level is what made me come back and purchase more. Thanks seller!
