Verified Purchase

I recently purchased this calculator because I needed one that was easy to see. In fact I purchased two of these. The price was reasonable, you can see the keys and window very good. it has a protective case and I like that. The keys are very easy to use. I am very pleased with my purchase of these Casio calculators.

Good for government tests

This is the perfect basic calculator for government tests. I bought this to take a HAM radio exam as they only permit basic calculators in for testing and my other calculators are considered “too advanced”. This worked perfectly as it allowed me to make the calculations I needed.

big keys and folding cover

over years i have had radio shack and kmart small solar calculators. this casio is by far the best. charges fast. the fold back cover is great. i can leave it on the desk without worrying if the keys are being damaged by sliding files on top. and the keys are large and with clear printing. casio is a good brand for all the items i have bought over the years.
