I bought three scales for my little mini-mill for the X, Y, and Z-axis, and have to say I thought these were a great bargain. They come with mounting brackets, scales covers, mounting screws, and end covers for the scales which was an unexpected surprise. Be aware that although these scales are advertised as Mophorn, they are labeled Vevor which was fine with me because they are of decent quality. Mounting the scales required some creativity, but that would be with any brand. Make sure you measure correctly for the length and keep in mind it will be easier to deal with a scale a little too long than one that is a little too short. The 3-axis display appears to be a more solid display than the Cozyel brand I have on my larger mill. Packaging was excellent and shipping was on time. The only negative was the display didn't have a ground wire in the package, but that wasn't a big deal since I made one in quick order.
