Summary: You have to be quiet close to the camera for it to work. i would in a studio, so it works fine! If you are a weekend backpacker adventuring in the woods to take glory shots, I recommend something much more stronger!
Summary: Paying anything more for an item that does the same thing as the one from an official company is absurd. I don't see why you would want to spend $30 on a DSLR remote control unless it has more features than just a shoot button.
Summary: I had wanted this strap for a while but didn't want to pay over $60.00 for it. It arrived relatively fast (less than two weeks I think) given that it came all the way from Japan. Product came in original Canon packaging and was exactly as I had expected.
