Get it.
Color: Green
I got the dark green one, which is really cool looking. At least if I have to add something at work, that will be fun😂. Seriously, for the price you can’t beat it. The keys are a good size, the display is great, has an option for AA battery, honestly, zero complaints here, just get it.

Good for desk (and maybe garage sales) - size super and very attractive.
Color: Purple
I have used 10 key calculators since the 60's on a lot of Accounting jobs but found myself retired with only a tiny little purse calculator. HELP! I looked at all sorts and sizes and finally decided I needed something with decent size keys and the basic functions . . and on thinking about it - I didn't even need a paper tape. After some search there it was and in several attractive colors and the size on my desktop is amazing. I recommend this machine to anyone who just needs retirement or other household and simple financial accounting. And, oh yes it is dual powered. ... show more

Good for the basics with a minor annoyance outweighed by the price and features
Color: Purple
After a relatives old cheapo calculator started dying because of a soldered battery I took it apart only to see the solar panel thing was fake, and it took a button cell battery, as well as other damage. So looked for a nice pink one for them that seemed better. The pink one here was more skin colored than pink so went for the purple?/lavender one which looks better. This one also has a solar panel thing on it so apparently will work even without batteries, but even better than that has a nice easy to remove battery cover. No having to undo very small screws and deal with button cell batteries. It also has big buttons and somewhat big display which is useful for them. They seem to like their new calculator and have used it every now and again. I think the only negative is using the memory plus ability. I have used very similar cheap calculators like this in the past that had the same layout and after you memory + a number than want to take a different number and divide by the memory number on higher priced calculators you can hit on/clear or clear and the number stays in memory unless you hit clear a second time or hit memory clear. But with these cheap ones if you hit clear it removes everything. Only way around this on these types is you have to hit the backspace arrow a few times deleting the numbers then you can enter said number then divide then "MRC" to get your answer. Idk if I am just wrong in how I do it but just seems weird and backwards after using more expensive calculators. But you can't really argue much cause for the price this does most basic stuff very well. ... show more

Not the best, but a great bang for your buck!
Color: Blue
Good price, ok quality. Buttons are not great and sometimes when you click the button, like if you’re not clicking in firmly directly in the center of the button, it won’t register that you pressed it.
