After a little more research I found then the Hama alarm clock (which cost almost only half!). And that's the kicker: I write otherwise quite a few reviews, but this alarm clock has really deserves times! Optical succeeded, easy to read display, operation with the motion sensor super (the Brown had not!), Stability good, low battery indicator (not unimportant at an alarm clock, and which does not exist at Brown) and last but not least an alarm, one would expect in a digital alarm clock.
Conclusion: Although, of course, must still show how long does the alarm clock, I can truly say with conviction that the price-performance ratio is sensational, I can only recommend this alarm.
