Used the 15 on a very tight pair of SpeedPlay pedals. Only managed to take one off, but not after causing dents in the tool's relatively soft steel.
Because of this experience, I'm not recommending this product.
In fairness, it is good for not very tight pedal installations.
All bike pedals are installed pretty tight, so this very soft steel won't do the very basic job of removing pedals. Unlike another poster, I was unable to remove even a single pedal before this became useless.
