Mistaken

Michael Colpetzer, Amazon
12 January 2014
  • Summary: Good calculator, NOT RPN, that's what I was looking for. I knew the price was too good to be true. I just assumed with an enter button and no equal button it was. I was not deceived by the seller. Just didn't do my research.

Very pleased with this HP 9s purchase

hazecoy, Ebay
10 September 2012
  • Summary: I wanted tactile keys (feel the click) on my calculator. Hp is the only company I know of that does this. It helps to let you know that you have pressed a key without looking at the screen. The price of this HP 9s was very low and the number of functions exceeds the needs of the normal user. I am very happy with this purchase.

This is not an RPN calculator

Kurt McClung, Amazon
2 May 2011
  • Summary: Reverse Polish Notation (RPN) calulators use an <enter> key and do not have an <=>. Look closely at the image for this product: This calculator has an <enter> key and does not have a <=> key, but it's not RPN. The owners manual is useless (written in Spanish). I was so excited to get an affordable RPN calculator and I deflated like the Hindenburg when I figured out I got rooked.

Good Calculator - Little Documentation

Amazon
8 September 2008
  • Summary: This is a good calculator with a lot of powerful functions. But, it has practically no manual with it and the one it comes with is difficult to understand. For the most part your on your own.

Let's move along, there's nothing to see here.

J. Paquin, Amazon
14 June 2008
  • Summary: I'm begging you not to buy this calculator. It is not just terrible, it is REALLY terrible. Oh, sure, it does a little graphing and will calculate the tax on a new Xbox, but what you can't see in this picture is that the graphing window has fewer pixels than the icons on your desktop (really). It is USELESS as a graphing calculator.

high school calcs

newton fisher "nerdly uncki", Amazon
29 April 2008
  • Summary: This calculator was for the 13 year old for school. Being the local `nerd' I got tagged with `picking out a good one' for her. Casio MS115: Scientific [no graphing]. This calculator is cursed by having its documentation not written by a native U.S. English user. Common commands and functions are easy to access.
