Review on π§ Ultimate Power Transmission Enhancement: Inch Chrome Steel Bearing Balls for Top-Performance Bearings by Sam Doucette
Caution: some sets may have rust
Ordered 2 sets for the marble run (Science Olympiad). One sentence was ok; In another set, each ball had a rusty stripe down the middle. Too much hassle/cost to send them back but I'm very glad I ordered 2 sets just to make sure one set worked.
Pros
- Pretty packaging
Cons
- I can't remember
