Excerpt: This is an essential piece of gear to go with a DSLR. The remote does what it is supposed to. I don't use a tripod without a remote, but you can also use it with the camera on the ground, etc. I agree with Emily above that it would be nice if it came with a little pouch that clipped to your camera strap so you would never forget it.
Excerpt: This was my first experience with a wireless remote for my Pentax Kx. I could not be happier with it! With past cameras I had a wire, which I trusted to actually take the picture, but it does limit you quite a bit on where you stand, how you stand and...there's normally a wire in the picture if you wanted to BE in the picture...photoshop anyone?
Excerpt: This may not exactly be something everybody has to have, but when I got my camera, it was one of the first accessories I bought. I haven't used it too much, but plan on using it alot in the future. Excellent for group shots. Very easy to use, but also easy to lose ( I stuck it in my jacket pocket and almost forgot where it was). You have to set the camera to remote mode and check the focus; that's pretty much it.
Summary: As far as I'm concerned remote shutter release is essential tool for many photography situations. This one from Pentax works very nicely. I do have a gripe however: it's small, black and doesn't have a lanyard ring and, thus, incredibly easy to lose. I ended up super-gluing a washer to mine so I could attach a (brightly colored) lanyard to it. I wish it came with a attachment point.
Summary: This little remote really works well. It allows me to be in the group shot and set the camera off as opposed to trying to set the timer and run to make it in the shot. I highly recomend this remote if you take a lot of group shots. It would also work well for close up shots where you did want to risk shaking the camera by pushing the shutter release button.
