The screws and washers on this model will rust quickly. New ones are quite expensive, and they'll rust quickly too, so it's a good deal if you're not concerned about them being new. This set includes the Dual Washer, which is used on higher-end models like the ATLAS. As many of you know, this part is said to improve foot stability, responsiveness, and power. If you use UNION bindings and want to try it out, please do.
