I originally used this once on a Nikon 10 pin camera and it worked well but was a bit slow on a clear day. It still worked. I tried using the second cable that came with the device to use this device on my D7100. It didn't work at all and even made my camera misbehave. Using an ohmmeter I found that the data pin and ground pin were shorted together. I paid for it. I deserve a working cable. I just need a cable, but I need it! I would be happy to return the defective cable.
