Summary: Actually, for dirt cheap. I occasionally need the 'advanced' functions, but the deal-maker for me was the fraction function. I do plenty of wood working and - old fashioned me - am still fond of the odd fractional method of measuring. I'm good up to 32nd's but I sure appreciate being able to calculate to 64ths and above. I recommend this device.
Summary: Awesome calculator for my physics and stats class. I do not usually use calculators but for someone who is a beginner in scientific calculators or rarely use them this is a great choice. very easy to use.
Summary: This calculator should have a warning that it's default setting is not standard and that adjustment will be mandatory to get it to preform like most other calculators. Display is not gray, but greenish and harder to see than most even with contrast adjusted. Stupid default setting doesnt give decimal, has strange Natural Book setting and smallest font ever instruction booklet is unreadable and lame, no User Manual included, you need to search online for that.
