Excerpt: I work in a office with no windows and I use low lighting, so I needed a calculator that was used batteries plus had a back up battery. I love it.It is big enough so I don't need my reading glasses to see the display and runs on the backup battery.
Excerpt: I absolutely love using this calculator. I have bought a couple in the past and enjoy using them. These calculator are really durable and continue to work even after I have dropped it on a hard floor from a height of about 3 feet.
Excerpt: Purchased this canon calculator to replace an existing product that the keys were sticking. Works great and the numbers are large enough to see. The calculator was purchased for a male employee in the office and sometimes with larger fingers it is more difficult to use the smaller keys. He loves it.
Summary: I have the old version of this at work WS-1200H and my calculator at home recently broke so I decided to get this thinking it was exactly the same as the one at work. When I got it, I noticed that there were three zero buttons on the bottom where my old one only had two.
Summary: Way too large in size. Probably 6 inches by 6 inches. Takes up too much desk space. Also, even though it's dual power (so partially powered by solar), you have to press the power button to power it up (instead of it automatically being on).
