Customer Reviews for VEVOR Linear Guide Rail Set, SBR20 1000mm, 2 PCS 39.4 in/1000 mm SBR20 Guide Rails and 4 PCS SBR20UU Slide Blocks, Linear Rails and Bearings Kit for Automated Machines DIY Project CNC Router Machines

Just received it and one of the roller blocks is binding up. Took it off the rail and cleaned out the metal flakes. Didn't make any difference.

WAY better then I could have imagined... holly crap... this was designed and built for way more then my home project :) but I could not be happier...

Thanks for good product. Boxing needs to be better though.

Exactly as described, fast shipping

It's super

I took a gamble and bought the cheapest rails amazon had to offer (these) and they turned out better than expected. Very straight, and only one wobbly carriage, which I expected and had already bought quality bearings and spare carriages in case there was a lemon or 4. No perceptible play in the other 3 carriages, for this price point The value is insane. Dont let those gatekeepers on cnc forums tell you you have to drop 500 on name brand rails! Just be ready to send back for replacements if they don't test out well.

This product worked well and it is as advertised. Rugged.

Easy to set up and use. Customer service was totally awesome when I had a question about the product… quick response and very helpful.
