Summary: This is a very poor calculator. I wasn't able to do problems in parentheses or able solve Sin, Cos, or Trig problems with the buttons they provide. Also the size of the calculator on the site is misleading; its super small. A waste of money and I had to buy different one!
Summary: Amazing calculator for the money. If you are taking Pre-Cal or higher you NEED this. What puts this over the TI-83 is that it can give you answers in standard form and decimal form. So if you input something like Sin(π/4) it will give you √2/2 as a solution and .707.
Summary: Most people use this calculator for high school math classes before calculus, I happen to use it for my math PhD qualifying exams, since no graphing calculators were allowed. This turns out to be the best option one can have, with all capabilities aside from making pretty plots.
This is by far the best scientific calculator I've ever run across

Summary: As a high school math teacher I see and use a lot of different calculators. This is by far the best scientific calculator I've ever run across. Use ability and function are superb. I tell all my high school students to buy this calculator. Best part is the fraction button.
