Prior to this, most portable calculators were either bulky or very expensive. However, Casio completely revolutionized people's perception of calculators by offering a device that was only one-third of the price of its competitors ( at that time, Sharp's EL-801 was priced at a whopping 39,000 JPY ), leading to an unprecedented success for Casio.
