These calculators are simply fantastic. I only tried one of them so far, so, I am unsure how many of the 48 calculators I purchased work; however, the one I opened worked wonderfully. Here are the things I learned about the calculator after purchasing:
*Each calculator comes in a different color trim.
*Each calculator includes it's own small box, directions and a case.
*The calculators are battery operated (with no solar power option). It says on back that the battery is not replaceable, which means this is really a disposable product.
*There are statistical functions (can calculate the mean, standard deviation, generate random numbers, etc.)
*This calculator can convert numbers between bases (i.e. BIN, OCT, HEX, AND DEC).
*There is a pi button, nth root, reciprocal, 1/x, n!, ln and log, all basic trig functions, including arc and hyperbolic, etc. Basically, this calculator (for 1 dollar) does everything except graphing.
*The calculator's statistical features and data tables aren't intuitive to use (I had to read and reread the directions to figure out how to use it).
*No solar power option AND the battery is not replaceable. There is a warning on back that the battery contains mercury, which means the battery should be disposed of as hazardous waste or recycled. Overall, I would have to conclude that this product is not environmentally friendly.

Get What You Pay For
Give these calculators a try for a basic class set. Very low quality, but I wasn't expecting high quality. The buttons are soft and not really reactive. 4 out of the 24 calculators were non-functional right from the package. I opened the 4 to see if it was just a battery issue but it wasn't. There is no solid circuit board, all the electrical components are laid out on thin plastic. Scientific Calculator at a dollar a piece was worth a try, but I would not recommend this calculator.

I have found one defective calculator out of ten so far. Nevertheless, the calculators are incredible deals. I don't think I could find any comparable scientific calculator for less than $7, and generally more. I now either sell (at cost) or give them to my students, if they need one.
