I agree with many of the other reviews - these versatile cams are great to place and to have on a rack. However, they're not very durable.

We have been using a set of link cams (red and gold) since spring 2006 and both have become unusable in less than a year of moderate use. The cable attaching the trigger to the lobe on the gold cam broke off rendering the cam useless. The spring also appears to be broken. The red link cam now has a hairline fracture in one of the lobes so its integrity is lost. We're not sure how this happened but it hadn't been abused (more than anything else on the rack). Both cams lasted less than one year of moderate use free climbing and a few pitches of aid.

Based on these issues, we recommend that the cable attachments should be swaged onto the lobes and trigger to replace the current 'snap' configuration and that the lobes be constructed of a material similar to a BD camalot in terms of its strength.

These cams are a great idea but I'll wait for the next generation of link cams before I purchase a set.
