Solid
"Bought this to install a WM bottom bracket. It took an incredible amount of torque to get into the frame. Placed the bike upside down and stuck a tool through the other opening so I could use two hands and my full weight in order to get sufficient torque. Tool was solid, didn't slip. Unlikely to ever need it again as I'm not planning on getting the bottom bracket out again, but worth the purchase to ensure neat installation"
