They were purchased to swap out the Casio A-178WEA-1A, which was used for just over 6 years before it broke beyond repair. Disappointed in the display's size and, consequently, the numbers' height. The display backlight was nice. Price. You may buy with delivery online for twice as much as you would in stores, where it costs $2800. Purchase of the Casio A-178WEA-1A is advised.
