What customers say about "Size & Weight"
HP 12c Platinum Calculator
  • The size, shape and feel of this thing that just helps me grasp underlying concepts better.
  • It is bigger in size, but it is fairly light and is still much smaller and lighter than a Scientific Calculator.
  • The right size. Fits in a shirt pocket or those little pockets in your brief case or backpack.
  • Compact size slips easily into a sportcoat pocket and you can rotate it continually in one hand just for fun!
  • The size is handy and fits into a shirt pocket easily.
Texas Instruments BA II Plus Calculator (Pocket, Finance, Black, Buttons, Battery)
  • The price point is one of the cheapest that I've found. It is pretty lightweight and is smaller in size than the TI-83 Scientific Calculator.
  • The item itself, is durable, a good comfortable size, and works quickly.
  • I have to say is that is user friendly, easy to access and to do simple calculations and its a very good size.
  • It seems very basic but has some great functions. The size of this calculator is nice.

What customers say about "Display"
HP 12c Platinum Calculator
  • I feel like the display is a big lighter than my previous.
  • This is a great little calculator that is easy to use, has readily visible display, and isn't too complicated.
  • The display is outstanding, and the numbers are displayed correctly.
  • The numbers weren't showing on the display very well, only parts of the numbers were showing and it was time to get a replacement.
  • The top row of the LCD works properly, but most of the bottom row of the LCD does not.
Texas Instruments BA II Plus Calculator (Pocket, Finance, Black, Buttons, Battery)
  • Very helpful in my Finance class. Easy to press buttons, easy to understand instructions and easy to read display.
  • It has a backspace key, a good single-line display, good contrast, robust design.
  • Everything on it seems to be fine. Features are good, screen display is large.
  • Nice display and fairly easy to learn. I now have one at home and the office.
  • I like it, but wish the display could be easier to read (numbers bolder or brighter).

What customers say about "Features"
HP 12c Platinum Calculator
  • It is sturdy and has a long battery life, absolutely no complains, recommended.
  • I've only had to replace the button batteries once that I can remember. Maybe twice?
  • I've replaced the batteries three times in 20 years. (Yeah, you read that right: three times.)
  • I've had the HP 12C calculator for a little more than a year now, and have used it quite often. Haven't had to change the batteries yet.
  • These use 2032 batteries and this model just died out and will show only a very light display but the calculator itself will not operate. Very disappointed.
Texas Instruments BA II Plus Calculator (Pocket, Finance, Black, Buttons, Battery)
  • The battery lasts a long time. I bought mine almost a year ago and it still works. I definitely recommend this calculator.
  • It has an auto off function, which saves battery life. Highly recommended.
  • The original is still working, and I've never changed the battery!
  • Great calculator. Superb batteries (I've never needed to change them) and it does everything I need it to.
