On the other hand, the screen is pretty large and the font it uses is large as well, making these digits easy to read even from a few feet away. On the one hand, the LCD screen cannot accommodate more than 8 digits, which is a little unfortunate. The Casio MS-80B is an elegant solution that takes up very little space on the desk, easily fitting briefcases and desk drawers. Add the key rollover to the mix, enabling this device to register every keystroke no matter how many keys are pressed at the same time, and you have yourself a pretty good overall calculator. Looking at its functions, the model incorporates command sings and can tackle tax and currency conversion and rounding. Also, this device weighs just 3.5 ounces, meaning that it is also more lightweight than its direct competition. At 4.7 x 5.7 x 1.6 inches, the model commands the smallest footprint among the calculators gathered on this list, making this device more desk space-friendly than most. What also contributes to the comfort cause is the calculator's size. But, even despite this little mishap, the calculator feels comfortable anyway. For the most part, the model is ergonomically sound, but the legs are a bit uneven, teetering a little when you press the keys. The ' ergonomic' remark primarily pertains to the 30-degree raised screen, enabling easy and accurate screen reading staring right at the numbers. The prints on these keys will not start wearing out or fading away anytime soon. The keys are large, and there's generous spacing between them, so you won't be misclicking all the time. The Helect H1001 is clean, simple, and ergonomic. So, provided you want something powerful, retro-looking, and long-lasting (the keys have been tested against 100,000 clicks each), the ONXE GX-200 will not leave you wanting more. Borrowing inspiration from scientific calculators, this model offers a rounding function (switch), a decimal location (switch), and lets you calculate square roots. Pressing the keys, you can also store the results into the Grand Total Memory. In addition, the calculator will let you subtract the number displayed on the screen to the one stored in the memory. What's not distracting is the model enabling quick and easy tax calculation. Of course, some might even like how loud they are, but there's a fairly good chance the people around you will find the clicking noise a little distracting. They're also quite loud, resembling typewriters' keys more so than calculators'. The tactile feedback is generous, the keys are well-spaced, they feel sturdy, have good travel, and a pretty solid rebound. While they feel a little shallow, they're also firm and snappy. Where this old-school approach comes from is primarily from the keys. The ONXE GX-200 goes old-school and we're more than fine joining this calculator on this journey.
