I really like these and while although some folks say they are just stamped steel and can be made in a third world country..they are very heavy duty and work quite well when set up properly..if I had to make one change on them, I would add Teflon strips to the faces of them..sliding a stained crown back and forth while adjusting the cut can scratch the crown, so I used black electrical tape..it worked fine then.  I will get some Teflon tape and add it later
