Summary: Bought this for our middle school daughter. Keys are smooth - easy to use, not sticky or clicky. does everything she needs it to! used it for a year, held up well, and it's still got lots of use left to it!
Summary: I teach Research Stats for both a private college and for a large, state university. I make all my students get this calculator. It's inexpensive, and it's powerful (capable of fully handling bi-variate data). Intuitive -- easy to use.
Summary: The display has a narrow viewing angle so you won't be able to see it depending on where you're sitting. The buttons are a little loose too. I knew both of these things before buying and still went with this one because the color was nice (haha).
