Compact size. Clearly legible display. Backlight by pressing a key for a few seconds possible - ranging display without lighting but fine. Every night is automatically set the time by radio reception. Manual setting - for example, upon receipt of the delivery is done by simultaneously pressing 2 keys. After a few seconds the clock is set correctly. Reset alarm is simple - but a bit strange. All in all a good product that does what it should, easy to handle and operate, and is also very inexpensive. For durability, I can not say anything yet.
