Perfectly functional. Seem to be accurately machined.

Product works great, bought for a trade show booth and are very stable.

They're not symmetric, but close enough many people wouldn't notice. Meaning: if you flip one plate over and perfectly line up the holes, the edges of the plates won't match. All 4 pieces were manufactured identically, so you can achieve evenness when you pay attention. I didn't use any metrology to confirm, but the bolt pattern appears to be uniform and evenly spaced.

Works well with the T-Track 80/20 rails.

They work well.

Worked perfectly for the Z-axis top of my CR-10S. Fit the horizontal and vertical extrusion bars, but you must mount only the inside 2 to ensure tooth nut parts are straight and holding the bar extrusion parts. Then the do the 2nd ones, then the outside end ones. That way it's holding all of the parts just right. You have to hold the 2 sides to ensure they are perfectly aligned with the horizontal and vertical extrusions. A bit of work to do, but you only have to do it once!
