Nikon ML-L3 Wireless Remote Control for Nikon D40, D40x, D60, D80 & D90 Digital SLR Cameras

The product came to me in a short period of time. It works like a champ! I really enjoy it!

You MUST be in front of the camera for the remote to work. I know that this might sound stupid but if you want to have your camera on a tripod and take pictures while standing BEHIND the camera, this is not what you are looking for (try with a shutter release cable)

The title says it all. It's cheap, handy, and works! The only thing I've noticed that's a little annoying (but not a deal breaker) is that my D5000 won't recognize it unless I'm holding it in my right hand (when using it behind a tripod). The lens and/or body must be blocking the signal when I try to use this in my left hand. I don't have a left/right hand preference when using it, but it would be nice to be able to use it in either hand so that I don't have to think about it. I haven't used it for self-photos in front of the camera, only behind a tripod. I recommend this. If I lost it, I would buy it again.

This remote does exactly what it's supposed to do. For the convenience and functionality it provides, it's a very good price.

I had this remote for more than a year now.
I used it with D90 quite a few times in this period

It would not fail for a cloudy days / dark environments upto 20-30 feet

It failed while I was trying to trigger it from around 20 feet on a bright sunny day.
But it worked same time when it was closer
So it might not work for long distance sunny days

Yes it does has some direction limitation (not 180 degree in-front of camera)
But we can trigger it from front of the camera...
from back of the camera (for macro shooters) it worked few times in some direction
So we should test its sensitivity ranges and direction/angle
This depends on where the sensor is located in your camera body too.

Overall its a good decision.
