No problems so far. Fits wasp 0.28 engine, with aftermarket drill start. The one that I got is made in Germany. Seller should mention that, to get more sales. ### ⭐⭐⭐⭐⭐ Well made *by D***E on August 12, 2023* Exactly as describe what was for sale ### ⭐ Cheap one way bearing....not worth buying *by A***R on April 11, 2021* Garbage!!! One way bearing internal roller fell out of it before even using it. I buy a lot of Traxxas product but I must say that i am very disappointed with this cheap one way bearing.
