Works okay as a alarm clock , but the clock display be way too bright and annoying . I be talk about the actual digital time display , not the sunrise simulator lamp , to avoid any possible confusion here . I have to put a piece of duct tape over it . I be really sensitive to light in my bedroom when I be try to sleep . keep in mind that I have the clock on the opposite side of the room , so I would not be tempt to just hit the snooze button and go back to sleep . if you be like I and find too-bright digital display annoying , you might want to get a different alarm clock . luckily I get this clock at half price , so I do not waste a lot of money on it .
