Summary: I intended this as a shopping calculator, to monitor costs as I push a cart around. To frustrate this, the OFF button, and AUTO OFF feature both erase the memory and display, making it useless to monitor costs on the go. The plastic case guards against accidentally hitting the OFF button, but the AUTO OFF feature will activate after a few minutes of non-use. Apparently this calculator doesn't have "independent" memory to retain results with power off.
Summary: This is a pocket-sized calculator with large screen and large number keys. It folds in half for easy storage in your pocket. Very creative and practical design . My arthritic fingers can easily cope with this.
Summary: Bought one for my godmother for her job. She loves it. It is much better than her old ones, the keys are very responsive, and the battery makes sure that the calculator works even when it is dark.
Summary: Works as expected. It has the features it claims to have and I have not had any problems with it. I like that it folds in half because I can toss it anywhere--pocket, purse, drawer, etc--and don't have to worry about breaking it.
Summary: My small calculator of choice now. I used a similar Casio for years and those were good too, but this one, being a little bigger, larger LED readout and a key layout I like better; this one is my new preferred. I use a calc at work quite a bit and the Casio unit was what I was using. They took quite a bit of abuse and kept working until I would basically destroy them somehow. I hope this Cannon can take wear and tear like the Casio did. If not, I'll amend this review.
Summary: I bought one of these calculators years ago when it had a leatherette cover. It was only a solar unit back then, so the fact that this works on battery and solar was a definite plus. But, the main reason why I bought it was to replace another calculator bought at a big-box retailer. Why? The keys were too small ... which I didn't even consider before buying the Casio ...
