Hello There, I can only recommend this clock !!! She has a great, modern design, similar to the Junghans Mega 1000 radio-controlled clock. It is more than worth the money, what does it cost including shipping (shipping Pearl House is the cheapest supplier on the net !!!). The voice has a volume is established and can be really understood very well. It is very easy to use / to adjust because the clock tells you about what setting (hour, minutes, date, year, alarm on or off, snooze on or off) a product contains, ie an increase, in the description is not specified. The battery is already in the clock and is sealed with foil, so that they will truly come full, there is a common button cell (CR 2025). The only special feature: You need a very small Phillips screwdriver (precision mechanic tool) in order to solve the 4 screws on the back, then pull the film from the battery cover back on it and the clock is operational / adjustable. Real futuristic design, really great !!!
