Build quality is good but dimensions do not match, I use this with Canon C200 grip. The Smallrig mount has removable screws that are also internally threaded to accommodate a different gripping mechanism. Unfortunately they countersunk the thread on the side of the Arri rosette enough that my C200's grip could only snag on a single thread, which is not at all safe to use, which I didn't do. This will most likely work if you buy an additional extension adapter like the CAMVATE M6 QR ARRI Rosette Mount Lock Extension for Filmmaker Rig, but it doesn't work with the Canon C200 Grip out of the box.
