This calculator is the best calculator I have ever used, period. The screen is bright, the battery lasts long (over a year at the least, and I use this calc everyday), and the buttons are big. For around $12, the quality of this calculator far surpasses its price point because I've seen pricier ones that are just fancy pants calculators that do the same thing. This one is sleek and very nicely designed. The buttons are also housed in a sturdy plastic case, which makes it really durable easy to handle. Love it!
