A+ Thanks

Hi NILO, thank you for your fantastic review! We're thrilled you're satisfied with your purchase. Come back anytime!

Perfect product at a fair price!

I couldn't believe the quality of these steel balls. They totally exceeded my expectations and the piano stool I was restoring looked fabulous.

Hi Michael, we're thrilled to hear these steel balls made such a positive impact on your project! The grading of balls relates to their accuracy. Pretty much standard for us is the same as those you purchased which is Grade 25. That designates a ball that has an accuracy in total sphericity and diameter of 25/1,000,000 of an inch. Rolex has nothing on the bearing manufacturers when it comes to accuracy. Thanks for sharing your experience.

Great company.

Great company and products. I just miss read the part and order the wrong size. But called them directly and got someone on the phone to help me order the right parts for my r/c car. So thank you so much for being a local company that still has great customer service and staff.

Hi Jon, thank you for your kind words! We're glad we could help you get the right parts for your RC car. We appreciate your support and look forward to serving you again! Be Well! Steve

Hi Mr. Linn! Thank you so much for your kind words. We're thrilled to hear you're satisfied with our service and shipping. We're a brick and mortar store that sells online, so we cannot hide behind our keyboards. We do our best to treat our customers the way we wish to be treated. It's old-fashioned and we plan on staying that way. Looking forward to serving you again! Thanks! Steve
