Review: Excellent bearing set - 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.
Review: Worked as intended - 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!
