I want to start off by saying this is a bit better built than I thought itd be. There are metal drive gears to drive the rollers (no idea if they are carbon steel or cast iron junk). The frame is not over engineered, but it is not under either. The rollers seem like the cheapest part of the machine, they are small and annoyingly knurled. The handle is crude and needed sharp edges ground off, but my real complaint here is it is too tight to the machine so you can't use it in a vise. I attempted to roll 3/8" round, but it was pretty clear that it was going to be a bad result so I stopped. If your goals are to work within the machines advertised limits, I think you'll be happy. It rolls 1/4" rd with ease. I do wish a larger version of this existed to roll 1/2", but this wasn't expected to be that machine. If your expectations are in check, this will be a good machine for you.
