Performs as expected for the price
2008-11-30I bought 2 of these 2 years ago for my Canon SD400. No, they don't last as long as the original Canon battery and yes, they've lost some of their charge capacity over 2 years. These are things I was expecting when I bought them. They're even cheaper now than they were when I got them. Might as well get a handful at this price.
Getting the job done
2008-11-15My original RAZR battery -- at a full charge -- was dying after a 20-minute conversation. I don't know if this replacement matches a factory battery in terms of how long a charge lasts, but it's made me forget that I had a battery problem and I can get a lot more mileage out of my phone now. With a motorola battery at $30-35, you can't go wrong here.

If you have a digital SLR, there will be a way to set all of these controls on your camera, but since they differ between manufacturers and models, you’ll need to refer to your camera’s manual to find out exactly how to change them.
All cameras, whether an ancient film camera, or a more modern digital, work in pretty much the same way. Photographs are taken by letting light fall onto a light-sensitive medium, which records the image. Traditionally, this has been film, but more recently, it tends to be a digital sensor. The more light that falls onto the film or sensor, the lighter the image.
Put simply, a camera consists of a light-tight box that stores a light-sensitive device (either a film or a digital sensor), a lens that magnifies and focuses the image onto that light-sensitive device through a hole in the box (called the aperture) , and a shutter that opens ...
