For the price they're decent but nothing i would put on my industrial machines. One thing i've noticed is that the blocks/wagons runs a bit different from rail to rail. I bought 3 sets (2x 1000 mm and 1x 600 mm) and all the 6 blocks have slightly different smoothness/feel to them. One side runs very light and smooth but another are pretty hard to push. I had to switch the blocks around to get my two rails on x-axis to run ish with same smoothness, and had to do the same with y-axis and z-axis. I guess the preload is slightly different on every wagon but nothing that made it problematic on my project (yet). I've tried them with and without load and with and without motors and then found out that one of the sides on the y-axis ran slower than the other. Oiled them up and cleaned everything without any improvement. So i had to switch around the blocks to find pairs that slid equally. Another thing i had with one of the sets was that the balls in the ball bearing nut just came out when i tested it with a stepper motor. I heard a bad metal against metal sound and suddenly i had 10-15 small balls on the table. For the price i don't know if i'm satisfied but it does the job so far, and the support from Vevor is as ususal excellent.

I'm very disappointed in the company because they cannot provide me with accurate drawings of the parts and will not contact the manufacturer and give me an email address to contact them with. I need drawings to present a proposal to a company for building an assembly.
