Difficult to read in bright light

Greer Sutter, Amazon
8 March 2014
  • Summary: Love the big keys, but found one drawback. It's extremely difficult to see numbers on the digital screen in the bright sun shining in my office window. I either have to shade the display with my hand or turn it around to face away from the window. Sigh.

Okay calculator

Brian, Amazon
19 February 2014
  • Summary: If the internal battery were to die, replacing it would be a serious pain because there is no easy way to change it. There are TINY screws holding the calculator together, so I'm guessing that it was never really meant to be taken apart to replace the battery. But, under normal lighting conditions, the solar cell is enough to power it.

  • Summary: I love this calculator. Big numbers and always accurate. Had to get used to the placement of the plus and equal buttons but after an adjustment period I am glad I purchased this.

Misleading Size of actual Item

Susan M. Dardis "sued", Amazon
8 August 2013
  • Summary: Item dimensions were supposed to be 8 x 10.8 x 2 inch. unfortunately that includes the packaging. Worthless information. The actual calculator is only 7 1/2 in high by 5 3/4 in wide. I needed the largest possible for an almost blind senior citizen. Very disappointed.
