Review: Junk - spindle the handle is connected to isn't keyed, so slips. Thats the negative part. Can be fixed with a bit of machining, but something the manufacturer didnt care about, so you shouldn't care about supporting the manufacturer. FYI issues: 1. limited to diameter. Something I didnt consider when purchasing. Hopefully that helps you make a decision. 2. Handle on bit doesn't clear my QTP top ,so had to rotate the handle on the bit which could interfere with other things or introduce a safety issue.
Review: If you need small balls, this WILL make them! - The replacement for the first tool (received without a cutter bit) was complete. After I insured all screws were tight, I attached it to my lathe using a quick-change tool holder. First thing I tried was to simply turn a rounded end on a piece of Delrin plastic. It took a bit to get used to the process, but I turned a very nice half round onto the end of the plastic. I then chucked up a short length of 1/2" aluminum rod. I insured the rod end was far enough out of the chuck that the tool would not impact the chuck jaws in use. I undercut a length of the shaft from about 1/2" from the end of the rod back about an inch and turned that down to roughly 1/4 diameter. Then I set the tool horizontal to the work, touched off at the dead center of the rod. I moved the cross feed out far enough that the cutter was clear of the work. I then started the lathe and moved the bit in until it made contact with the right hand end of the work. I swung the handle left and right and knocked the edges off the work. I advanced the tool and swung the handle between the center of the end of the rod and back as far as it would go - that is, until it struck the undercut section of the rod. I continued advancing a little at a time until I was cutting the entire surface of the nicely-forming ball on the end of the shaft ! Once I had tool cutting during the entirety of the swing I stopped cutting and polished the ball and shaft with 400 grit sandpaper. The result a smooth, shiny ball about 3/8" diameter. I hadn't measured anything exactly in this test, just wanted to see if it worked. IT DOES!! Feed slowly and use enough speed to prevent chatter. I think this will work for all the small projects I may want balls for. I will try drilling and tapping the next one with 1/4-20 thread so I can screw it onto a "handle" - this is still test, try, learn mode. But think it will get lots of practical use in the future.

### ⭐⭐⭐⭐ Not the best build quality and a bit small but...
*by I***E on January 31, 2022*

Took some trial and error and a few you tube videos to learn how to use it but it does work quite nicely. I seriously doubt your gonna be turning steel with it. But I lost the ball on the end of my back gear lever and turned a new one with it out of delrin and it works really well I tried it on some aluminum and it worked but was a little chattery and the finish was so so. I haven't tried steel and probably won't
