Does what it should and appears well built. I’ll definitely buy again

Was very happy with the quality. Spun the lead screws with a drill at several hundred rpm’s and they didn’t wobble at all. Bearings are all tight and no play in the bearings or screws. For the price you can’t beat it.

These are good rails.

Linear rails are excellent quality . Super fast shipping. Box was damaged but contents were ok .The hole in the box was big enough for parts to fall out. FedEx would not be my first choice for shipping anything.

It looks like I'm one of the fortunate ones. All parts arrived even though the box had a bit of an opening in it from shipping damage. My main issue is that they don't package this set appropriately. It should be double boxed to ensure everything arrives and arrives undamaged and no parts fall out.I am using this set to expand the Y axis of my home built CNC. I have assembled everything just to test fit and it seems to have very little, if any slop/backlash. I'm pleased and I feel fortunate that I got all of the parts and they seem to be precisely machined.The price is fantastic for the quality I received. The blocks and rails are 5 star. I deducted a star for inadequate protection of the contents.At some point you'll probably be trying to mount this to something... or something to it... or both. The threads are 5mm - 0.8 for the blocks and ball screw mount. The through hole in the rails is about 6mm but the two different 6mm machine screws I tried have a head too big to fit the counter sunk hole. I'm hoping to find a 6mm machine screw with a small head, if not, I'll use the grinder or have to revert to 5mm screws to mount the rails.

This is insanely sturdy and accurate. Literally no play at all when i slide the blocks around. Going to buy more next time just wow!

Good stuff if on budget fast shipping really could do variety of things with these hope I can get the job done.

Great product thanks vevor nice to get good stuff at reasonable prices when all the other companies sell us same stuff will jacked up profit margins

Used it to build CNC router. It’s very solid, good product.

Overall met expectations at a low price, however, it did not come with the plum coupling as mentioned in the description. However, the high cost to ship for returns was more than the cost of the coupling
