My husband rides those and he loves them. I was miserable with them for two years, used many pairs from the lower model to Ultegra, and eventually gave up on them. I observed that tension was very inconsistent, quite tough to unclip even at the loosest setting, and absolutely terrible (not to say dangerous) when wet and/or dirty.

My husband *never* had any issues with his.

I thought it maybe had to do with quality control. But I'm glad I returned to mountain SPDs with very stiff shoes (Sidi Dominators).
