This is a nice tool for the money, instructions are basically useless for any novice, not even a schematic to see where parts that have vibrated loose in shipping go. As far as the tool it's actually really cool, a lot of details in the build. For me, the handle that moves the ring holder was way too loose,,,very sloppy, I machined .005 off of the shoulder bolt that holds it on & it now works smoothly & without any jankey action. I did add a pushback spring (siliconed on) to move the ring holder back automatically,. easy fix. All in all worth the dough.
