I must say that I can't quite understand the folks who didn't like this clock. The case is 3 1/2 inches long by about 1 3/4 inches high,......and the display numerals are almost a FULL INCH tall. It's easy to set, and can mount with the provided tape or screws. You simply touch the right side and the blue light illuminates the dial perfectly. The black case is nice looking too. Keeps perfect time also. The display numbers are huge,...... and can be read from across the room. Highly recommended.
