These clocks are very cool - especially at night with that blue neon light glowing. The numbers are large and easy to read. I set the time and put a battery in and ran it overnight - next morning the time was right on. It's quiet, no noise at all. It also plugs in directly to an outlet.
Manufacturers detail: This wall clock features a classic tin sign advertisement inside and has a chromed plastic case and a tin metal face. The blue neon light works on the included A/C Adapter and the clock runs on one AA battery (not included). The neon light can be turned off while the clock continues to run. Great addition to Restaurants, Diners, Bars, Rec Rooms, Game Rooms or Garages.
