I bought one last year. Or tried to…
Shitty experience from start to finish, figuring out how to send it to them. (their own instructions were incorrect)
Finally got my crank back from the factory install 2,5 months after paying.
It never worked!
Then fought them for another month or two to get my money back as they never offered to replace.
Never got a reply from them using email or DM on various social media unless writing negative comments publicly on their FB page which would prompt a “can you send us a private message” every time.
Now I have an extra piece of plastic on my left crank and Favero Assioma pedals.
