I use it in clock shop between set top boxes and game consoles are not the modern look looks good. As said earlier, you have to reset the ignition. 3 brightness levels + but even the weak is strong enough, in a room that seems to me to be too. Large beeps every support during setting, which fortunately does not change time every 5 minutes. An alarm function and date I will not use, but large numbers / modern look / reasonable price this is a good summary of the product. The AC adapter is included as well as a button battery in case of power failure.
