"Finally I found a calculator that has big buttons and a large readout."
"Great hand-held calculator with larger keyboard and larger numbers in the panel which is great for those of us whose vision isn't what it used to be."
"This is a great handy calculator and it works fine."
"I used it on my very busy loan officer desk for 17 years, spilled coffee, soda, and ice cream on it and it still worked! I wiped off the underside of the keys and washed the silicone pad and the reassembled calculator works perfect, like new!!!"
"The buttons on this one are just placed slightly differently (due partly to the fact that this one has an 'off' and the other didn't), so I continue to make errors, thinking I've pressed a decimal, when in fact I've pressed the equal sign instead."
"I share the opinion of other reviewers here who lament that this calculator does not easily allow you to add percentages."
"Prior to purchasing this calculator I failed to notice that the decimal key was in the bottom row center key."
Solar (works only when it is bright) and battery (one AA battery not included). Two-way Power: Solar (works only when it is bright) and Battery (one AA battery NOT included).

"I bought this calculator for basic imperial (foot/inch) measurement system entry and math, including fractions, but have found that it excels in the feature set it offers - including circle, arc, area, volume, and right angle calculations. The calculator itself is feather-weight, but appears to be made of a tough plastic. There is actually storage for the printed pocket guide in the form of a built-in pocket on the back of the calculator. I went back and forth a few time trying to decide between this model and the trig model, but this one has some built in calcs the trig model does not have, and I've found that this model's right triangle, circle/arc, and degree entry capabilities meet my geometric needs. Amazon had the best price on this calculator that I'd seen to-date at the time I bought it."
"I this all the time when I am out in the field or at my desk to calculate feet and inches."
"If you do any work with construction like cement pads, carpentry, even conversions, get this little jewel for the farm or work shop."
"Its very easy to enter foot/inch units and converting between units is a push of a button."
"If you are handy around the house or run a home repair business, better add one to your tool box."
"Be advised an armadillo case came in the box with my order of this product, you might want to wait before ordering the highly recommended armadillo case separately as you too might get a "bonus" package with a case."
"I have the app on my phone, but it eats my battery up while I'm working with it."

"I like the big buttons and bright display, but it's definitely not "mini.""

"Looks great, works great and easy to use!"
"I like the paper feature of this calculator, it allows you to look back on everything you did, even to save the tape with your records for later, obviously the ones without paper makes you write everything out, it is a time saver all the way around."
"Very pleased and happy to be able to replace the one I had before, it was exact model, but after a many years it finally quit printing, why because it was my own fault!!"
"Has a large keyboard, once I figured out how to operate the adding machine it does a great job."
"However, the paper roll was not held on securely on a cheap plastic holder and that roll or paper would constantly fall off."
