I decided to post this product because of my really good experience with it. I have had an older version with a 9-pin connector for my Nikon D200 since 2006 and for 6 years it just worked. It does not have fancy features like intervalometer and LCD but I do not need those in a remote control since the cameras I have already have those features. As such, this under $30 remote does what I need it to do and does it very well.
I just bought this ALZO Wireless Radio Shutter Release version since the Nikon D600 does not have the 9-pin connector of the previous generations. This one plugs into the camera control / GPS connector of the Nikon D600.
Have fun shooting from distance or capturing self-portraits. Kids love to use this for family photos too! :-)
