Summary: This calculator does what it's supposed to. I don't have a problem with the size. I actually thought it would be bigger but this size works perfect for me. I was a little bit disappointed because instead of getting two pink buttons as displayed, they were purple instead and pink is actually my favorite color. Other than that it works fine.
Summary: I began using this calculator as soon as I took it out of the box. It is the perfect size for my desk, and very user-friendly, as far as the layout, function, and feel. It's great that this is solar AND battery powered, as I have had calculators in the past die on me quickly. Also, this calculator has a square root function, which is awesome, as some calculators of similar sizes do not. This has met and exceeded all my needs thus far, I HIGHLY recommend!
Summary: This calculator is a much smaller then I expected, but I guess that's partially my fault, as I didn't pay as much attention to the measurements, but its tiny, and the buttons are very small. More importantly, the buttons on this calculator are positioned terribly. If you look carefully at the picture, you'll realize that they are not positioned logically for the things you are likely to use this simple calculator for.
Summary: My former calculator (a very small "freebie") was constantly getting lost on my computer table. I know, you can do the math in the Google search bar but sometimes that just isn't convenient. This is just right, big enough to stay in sight and small enough not to take up too much room. And the battery seems to be holding up really well.
Summary: This thing is tiny. So tiny I can't get my piano fingers to accurately hit the buttons I want to press. Maybe I should have read a bit more about the product size, but really, who would want a calculator this size?
