5.0 out of 5 stars Really good, heavy bearings
Reviewed in the United States on May 19, 2024
Very nice bearings that I use for projects. Very symmetrical and pretty well polished. Not quite chrome-bright, but it's a good clean steel without even a speck of rust. I can recommend these if you don't need a mirror polish.

5.0 out of 5 stars They’re balls!
Reviewed in the United States on August 24, 2023
So, I purchased these and some high powered magnets and, (when they say to be careful, thy mean it, those things will fly together and smash a finger! You cannot move fast enough either! Then, mine smacked into each other, breaking a magnet, so be careful a ) I set up my own dent repair kit to use on a couple of my saxophones! I ended up with 1-1/2”, 1-3/4” and 2” balls. I glued a scrap piece of leather to my 2 high powered magnets (bought here for $20-ish) I also bought these steel rollers for rolling out dents and a dent chasing hammer here, on Amazon, I didn’t spend but maybe 80-100 bucks! And a dent ball magnet kit alone, at the music shop is like $1200-$1500, no joke! They work great, and saves a ton of money, but there is a learning curve, and realize, you may not get the dent removed 100%, but 80-95% isn bad!

Rust really fast and come in a very strong smelling oil. Other than that, they do the job

5.0 out of 5 stars Good for holding filament spools down in an AMS when they get empty
Reviewed in the United States on March 16, 2024
I got these to put into the center of my 3d printing filament spools so they don't flip around all crazy in the AMS. Works well, though I did have to make a custom cylinder to print and hold them in place since my spools don't have ridges you can just put the ball into.

1.0 out of 5 stars Will Rust your paints
Reviewed in the United States on April 8, 2024
Does not claim to be stainless steel however who in the right mind uses anything else for "Paint mixing". Do not use this product to mix anything you don't want to inherit a red hue and micro rust flakes.

Essentially garbage because it pollutes whatever liquid it rests in. Thank you for ruining my paints and varnishes.
