Product shipped fast and arrived on time. Parts arrived in factory packaging with good finish on products. Dimensions are to spec as stated with no visible defects. Unfortunately mine arrived without any set screws. Had some extra M4 screws but was annoying getting the little wrench to install them without getting the screws. Couplings are otherwise performing perfectly so far.

We needed to connect two 5 mm rods in one of our inventions and these worked exactly as we needed them to.

With a full machine shop in my basement, for this price and quality, I would be a fool to make my own. These are very good couplings, and I put them on 1/2 my commercial printers already.

I'm trying to use these to life a monitor rig. Admittedly it's fairly heavy, but these couplings keep slipping and coming off even though I put them on with locktite. Having the two screws 180 degrees from each other means you only have two tiny contact patches or you have to just use one set screw. This may ok for some light applications, but I feel like it would have been better to just have a more traditional set screw offset.
