I think it's just a joke from Philips, this feature, which is perhaps 20 cents in manufacturing cost extra to block only the more expensive by 1/4 clock. Something like my 20 years old radio with digital display has already had.
There are 30 days money back guarantee Philips Fortunately ...
Pro:
+ Ingenious Weckkonzept
+ Stylish design
To use as a reading lamp +
Neutral:
Radio useful operation for a little work in well, 3 "sounds of nature" sufficient
Con:
- No automatic Displaydimmung although touted to product page
- No radio clock
- Insufficient power failure protection settings (on reserve battery, only short-term memory -probably via capacitor over a few minutes)
There is no USB connection, such as when the previous version -
Conclusion:
As such, the clock's top, but without the automatic dimming is missing a very useful feature. Although you can dim the display manually, but do not want to constantly switch back and forth, either the clock is not disturbing at night and during the day can not be read, or vise-versa.
And I'm still mad that it was not visible before or now I have to buy the more expensive model for a 20-cent function that was supposed to be standard.
You can tell just that Philips wanted something (and found) has to have different product versions available. Why, therefore, must be eliminated actually useful functions like dimming and USB connector, although the were ever present in the previous versions at the same price, known only to the manufacturer .. Well, maybe it gets in the next product revision the perfect alarm clock ?! ;)
Update as of 11.01.2013:
After a long consultation with the recipient but now there's a star more. The lack of automatic Anzeigendimmung is indeed still very bad (in my opinion Kundenveräpplung), but since the alarm otherwise does exactly what it should, but ultimately it is enough for an "OK".
