I've been using this particular model for three years. I use it mainly to take pics of the various items I sell on eBay, and I've found it to be fairly reliable, although the picture quality & resolution isn't always consistent. Some of my photos will be reasonably crisp & clear; others will be a bit muddy. Of course, this could just be due to a lack of photography skills on my part, since my parents also own one of these, and their photos consistently come out nice and clear. They use theirs to take reference pics and event photos for the various organizations they're involved in.
