This product would get 4 stars from me if it was less than $25. At first glance, the product has a nice metal back and a sturdy 3D printed stand adapter. The 3D print I had was too small and I could easily pull the monitor out of the adapter. This is not good if you want to mount it vertically. The VESA part itself fits perfectly. The only thing I wish they would change is that the metal back is centered on the monitor instead of low down. So if like me you have two different monitors they will be misaligned unless you can change the individual height. Otherwise it does what it should and can be installed directly. There are no instructions in the box, but there are nuts and bolts to attach to the VESA adapter part.
