Summary: It works. But not all the time and not from very far away. Works best from within one foot away from my camera. I used it to get into the picture, but my arm was extended, point at my camera. It would not work from inside my light weight windbreaker pocket.
Pros: Small, easy to use. Fast service from Crutchfield.
Cons: Does not always work, must be close to camera, and can not be used if covered by a pocket for concealment.
Summary: Be aware if you are purchasing the 400/- one Nikon ML-L3. Its a fake product, you can browse on google about this identify the original product. But its working fine as like original with no issues, so what you pay is what you get. Anyways i m not returning back this. happy to use this.
Summary: It's a good basic unit for remote shutter release but has a great deal of difficulty if you are using it from behind for stable shutter release or if you are using it from more than 10 feet away when firing from in front of it.
