Summary: I have to say that this is a pretty good accessory to have. The only con that I have ran across is that it does not work from directly behind the camera, but that's solved by using it from the side. This is a must if you want to do long exposures.
Summary: It works as promised, no problems. Found it online at Crutchfield, and noticed the C'ville store had it in stock. It's great to have a high quality national retailer based here in town. Thanks, Crutchfield! :)
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.
