I purchased these in October and November of 2010. One has been used quite a bit and has some scratches from the fork (hey...it's a big heavy Kona bike...) the other was used once and is in perfect condition. Comes with instructions, hardware and 4 keys (2 for each mount).
These are solid!
No need to keep them as I now have a shell with Thule racks.
Price paid: $129.90 total
