Summary: I bought this calculator five years ago and only used it periodically. It is very light, has a large display, and the keys are have a good feel to them. Unfortunately, it developed a short and no longer functions. Frankly, I expected it to last longer than it did (considering the light use it received) and cannot recommend it.
Summary: I've had one of these for years, use it every week to pay bills. It's the right size, not too big. I just bought several more - one to keep in the kitchen area, one for my niece for schoolwork, and a couple extra for stocking stuffers. Sure, most computers and cell phones have built-in calculators these days but there's no substitute for a hand held when doing certain projects. Inexpensive, dependable, functional -- what more could you ask for?
Summary: Does basic stuff that for day to day math Small fits into pocket easily Dual Power (solar & battery) Its total grey color including buttons (except power), It would have been nicer to have contrasting colors for FUNCTION button and different color (say cream ) for body!
