This clock is simple, light, and it has a cool gimmick. Clap and it displays the time. It only has one alarm feature but that's fine. I can live with it. There are some things I cannot live with. The primary one is the battery use. You would think a clock that you have to clap for it to display would be great at conserving battery life, but it terrible. I have tried long lasting batteries, regular batteries and the most I get out of this clock is 3 months. That's 8 triple batteries a year! More than my TV remote (which I use regularly). There should have been at least an option to use an AC adapter for this clock, but there is not. This clock is a huge disappointment.
