For a dollar, it's a wonderful camera!
I have one of the Vivitar's as well, and I think its quality (really? we're talking about "quality" for a dollar camera?
) is probably not as good as the Vivitar. I've been picking these up, as well as some other plastic cams, to use in a course I'll be teaching this fall about "alternative cameras", so I've been testing them out prior to having the students use them. Also slated for use are some pinhole cameras made from Altoids tins, matchboxes, and more $1 trash cams, as well as a dozen Brownie Hawkeye Flash cams, Holgas, Blackbird, Flys, and a bunch of other stuff. But I really did enjoy using this Ultronics; the exposure was a bit over, but I tweaked it in CS5 to make it more presentable. Probably a lower ISO - 100 or so, or I think maybe they recommend 200 - would be better, but I used what I had, some 400ISO Walgreens' film from their bargain bin. For 72 cents I couldn't really be too picky about the ISO. It's definitely in the budget range for college students!
Short answer? It's fun! Easy to carry, and no need to worry about it being stolen! And, it fits in almost any pocket. I'll keep using it, just for the fun of it! Actually I carry a bag of 15 or 20 plastic cameras on those days when plastic is the answer!
