slips off super easily

  • Familiarity: I've used it several times

Not sure if it is the fault of raceface's BB design, or this tool, but man this thing is a pain to use. As soon as you apply torque the tool starts slipping off the bottom bracket. Very hard to use with your bike in a stand or upside down. Best way is to lie bike on its side so you can get downward force so the tool doesn't slip off. Gets the job done, but very poor design.

Have you tried this inn comparison to Race Faces BB30 Tool? If so - which is better option?
