Surprisingly good quality chuck. Solid and well made. I machined a cast iron backplate for it and installed it on my 9 x 20 lathe. (I think it is the perfect size for this lathe; imho a six inch chuck would be too big.) The jaws seemed a bit sticky at first but this was solved by a thorough cleaning. The only negative was the number of sharp edges on the jaws and chuck face, but again this was easily fixed. I chucked up a back gear housing and adjusted center to within 0.0005, (the limit of my DTI), so it works well for me. I would buy it again.
