Since I wrote that 2 months ago, two of the receiver portions of the Nikon set-up have failed. The first was replaced at no cost by Adorama, and they are doing the same again. I bought a similar, although a bit less elegant rig (Alzo), which is working well through the past two rather rigorous (500+ clicks) weekends. I don't know about the long-term durability of this accessory, but the Nikon one sure has it's problems. I have yet to determine the actual failure, but in both receivers, the light indicates that it receives the transmitted signal, but the shutter doesn't fire. This could be a setting somewhere, but the cameras (D600, D7000) fire on the Alzo remote and both wired remotes I have tried. The Nikon setup cost nearly $200 (Transmitter about $125, and receiver about $65) - the Alzo about $35 for Tx and Rx. Good luck to anyone who goes down this path.
