I bought mine from the NiceCNC store on Amazon. I really like how this is built, I like that it's adjustable and shifting felt really good.
I was disappointed that after about 2 months of using it (with no drops or crashes) the shift arm bolt sheared off in the shift pedal. It looks like it was cross-threaded at the factory and the threaded bolt couldn't handle the force applied so far from the mating surface.
I am hesitant to order another one, and haven't gotten a response from my attempt to reach out to customer support because it's an Amazon order.
