Worked well for about 1000 miles, was easy to install - now under load (climbing in low gears) it makes an audible clicking sound. I've checked the torque, reinstalled it with fresh grease, and it still clicks. Seems like it was worth the low price but didn't last as long as I had hoped. Going to replace it with a Wheels MFG BB.

Worked great for a while. At 3400mi the non drive side bearing makes low thumping. Under load up hill does nothing, on descents and flats become more frequent. Everything at torque spec and drive chain components are still sound except for bearing cup after disassembling
