La herramienta se siente de calidad, tiene buen peso y rigidez, de momento la he usado mucho para quitar CenterLock y bottonBracket BB-MT500 y 501 y funciona muy bien sin queja y al ser larga se puede hacer palanca y aflojar de mejor manera.

Better quality than I had expected. Decent weight without being cumbersome. Fit my bottom bracket easily and accurately with zero noticeable play. I don't know when/if I'll need this tool in the future, but it did exactly what I needed it to do for this project. Stored properly, im sure it'll outlive me.

Great tool to have around the shop. Well made; smooth edges. It’s fairly narrow for tight fits but sturdy enough to put some weight on it if necessary. Four different openings for whatever needs loosening. Only drawback is there isn’t a way to attach a torque wrench. I knew that but bought it anyway.

Originally purchased a socket-type which wasn't deep enough to allow the crank shaft fit in and had to be returned. No such problem with this one. Long enough to exert enough torque but no way to control that (as my bottom bracket specifies) Would be nice if a 3/8" square opening was provided to engage a torque wrench.
