I have owned several other clocks before and I have to say that this is the best clock I have ever owned. The clock is easy to use and set up. I had it up and running within 5 minutes out of the box. It works really well if you want to wake up early in the morning. It's loud enough that it can be heard throughout my whole house and only be at half volume. The screen show green numbers if you're wondering what color it is. The nice thing about this clock that I liked about it is the fact that it has it's own separate battery inside when you purchase it. It comes in handy because there's no need to reset the time when there's a blackout or if you're moving it. This is really the reason why I bought this clock and what makes it different from all the other clocks out there. There's no hassle when moving it just unplug and plug back in; there's no need to reset the time. This clock is still going on strong after two years of use and accidental drops. Theres only one bad thing about it though; the radio isn't the best and it take a while to find a station with no static.
