Texas Instruments make quality products. I use my TI-30XIIS daily at work. It is easy to use, and the screen is clear for reading. I have dropped this calculator more times than I can count, and it looks no worse for the wear. After 2 years of use, none of the buttons have faded, and I still haven’t had to replace the batteries.
