Summary: I have this calculator at work and so far I've not had any issues with it. It runs off solar and battery power so you don't need to be in a brighly lit room for it to work--a huge plus if you've ever had to find a brighly lit area just to power up your calculator. I haven't had any issues with any of the buttons sticking and all my calculations have come out accurately (I had to use longhand just to make sure--lol). No complaints here.
Great size, functions perfectly well with solar power, and price can't be beat!

Summary: We love these calculators and have purchased many throughout the last year for everyone in our office... Everyone wanted one! The overall size of the product and buttons make it so easy to use. And, unlike other solar-powered calculators we have tried, the numbers on the screen are never dim, fading, or hard to read. This calculator doesn't have all the extra functions that others have...
Summary: The buttons depress halfway sometimes so it is hard to tell if a number is entered correctly without looking at each number as you enter it. Numerous errors each time I use it. Unfortunately, the calculator is not returnable.
