I've taken some great shots with this remote, fireworks on New Years Eve I was able to enjoy the show with friends at the same time as taking pictures, and some great shots of birds at a feeder. If there was an On/Off Switch I'd be a lot happier as I'm sure I'll need a new battery just when I want to use it. Great range, I was more than 150 feet from the camera taking shots.
It makes it easier to take pictures without accidently shaking camera and the big plus is I don't have to run to get in picture.
