While I haven't been using these long enough to comment on the long term durability, they seem like they will last awhile. It is nice being able to adjust the tension of clipping in and out. It is a must for first time clipless users, so they can build up their confidence and increase the tension as they become more confident. They are a heck of a good buy considering how cheap they are and the beatings they appear to be able to take. I'm not saying they are the best pedals out there, but for the price they are wonderful.
