Works as advertised with plenty of options to choose from. I use it to replace the bearing on my honey extractor. So far, after a year, no rust and works as advertised. Great value for the money.

Meets all needs

Needed a 3.5mm ball for my Dewalt DCF809 since it's chuck survicing kit came with wrong size. This kit more than paid for itself already with just a single ball used. Invaluable!

Now I have a life time supply of multiple sizes of balls…1 size perfectly fit the ball detent on my Milwaukee ratcheting screwdriver.👍🏻

The plastic parts box comes with a variety of small metric ball bearings.

Quality and works Great .

Lots of balls in lots of sizes. Great for projects or for dropping on the floor to cause yourself or someone you dislike great distress.

Had a little mishap as I opened the box, none of the bearings fell out, but became displaced inside the box. I decided to reorganize and cut flexible magnets to hold them in their box better. As I did so, I came to find that I did not get the full count of each size of magnets. Usually 2-3 bearings short in each size from 5.5mm and smaller; this is why I am giving it a 3. That said, the ball bearings were pretty much on the money to within 1 or 2 100ths of a mm as measured on my digital caliper to put them in the correct box.
