I had been using another type of calculator that was just a little bigger and had the screen that was on a tilt. I got to the point where I felt it was just a bit large for me (I am only 4'9"). I liked the Texas Instruments name and the price, so I ordered it. When it came, I started using it right away and really liked the design, and how easy it was to pick up and use. I do not like the fact it does not have an off button as my other one did, and sometimes I hit a button below the one I wanted to hit. On the whole, I do like it better, and am glad I had chosen it.
