This calculator is amazing the second screen is really useful. I had purchased this for that reason because a co-worker has one too. Very friendly to use and the numbers are big enough for me to see.AwsomeExactly what I wanted for calculating sales tax. Highly recommended.Just what I was looking for to replace my big old desk calculator.I have never seen dual display calculator in my life. It's very convenient and shorten my work a lot. I'm very pleased with the product and would buy again if needed.Honestly, you get what you pay for. I have been using this for a month and it gets the job done. Nothing tooo special, but its a calculator.This is the best thing EVER. The solar power works great even in low light situations. I love the huge buttons that have a deeper “press” so there aren’t any accidental numbers hit while entering data. The second screen is genius and super useful. I can’t tell you how many times I’ve had to write down a number to be used in another equation, or that thing we do where you say the number over and over out loud until you use it in the next equation. Wish I bought this a long time ago.Product arrived fast and works great! Office workers like it also.Used daily as an Accountant as desk calculator. Highly recommend. Non slip base, keys well spaced. Overall less re-keying, inspires confidence. Display is clear and second display window is pure genius.Casio has been a great brand that I have used for many things from calculators to watches.I recall having a calculator wrist watch as a kid that worked for over 5 years even with water and other things a 6-10 year old puts his clothes and himself through. It eventually ended up getting lost before it had problems.This specific purchase was made to replace my dads old casio calculator that had started to have fading numbers and giving him issues with calculations - mind you his old calculator has been with us for over 15 years. He is facing a few issues with getting the hang of the dual screen (not sure how long it will take to get used to it) his calculations don't rely on the dual screen though - and as a regular calculator he has been very pleased with it and it is quite nicely designed with tactile keys. Overall the product exactly as expected and am happy to recommend it to anyone who wants the old school calc instead of using the one through a phone - some, like my dad prefer it that way.(Photos to be added - If, for any reason the experience changes, this will be updated accordingly with *** to indicate start, end and date of the update)Hope you found this review helpful in your decision :) Happy shopping!F.A.This is the most incredible calculator ever. The second screen is genius. It completely changes what you can do with a calculator -- do a long series of calculations, then park the result on the second screen, then do another set of calculations, then use the results of the two sets of calculations together. I guarantee that you will use the second-screen feature every single time you use this calculator. Life-changing.I really like this calculator for it's size, and for it's dual displays. There are multiple ways to use this set up - from keeping totals, to doing two different calculations with each display! Very handy.I love this calculator! I'm a bookkeeper and the buttons are nice and I love the second screen.
