Technical aspects:
Positives: -The gradient (The main reason why I bought the 3510 instead of 3505) is very nice, from reddish to yellowish to (penultimate and final stage) white and bright exceptionally pleasant light, not bluish, as you would with a LED. indeed, has often feared.
-The Maximum light output is impressive and the evening almost replace the normal room lighting
-The Sunset function is a nice gimmick, especially when you still want to read a little, but not too long. Since I hardly have problems getting to sleep, I can not really judge whether the light supports.
Neutral:
-The Clock is relatively large, but can be found on the nightstand quite a place.
-The Buttons are mounted at the top and not illuminated. That makes it a little difficult at first to find the right ones, but you get used to it quickly.
-The Clock has no built-in battery for bridging. The display If you are ausstöpselt him away quickly. However, the time appears to remain somehow saved, at least I was able to ship it in the house from one room to another without the time to re-adjust to.
Negatives:
-For The price you would have to install a radio clock. Bothers me personally a little, but would be nice.
-Ebenso You would have at least able to install dual alarm for week and weekend. This sets the alarm clock every day, which is always the last alarm is displayed (However, one can make the morning with a trick that the alarm for the next day at the same time is already provided. Instead of the alarm button Click and turn off the alarm, you can use another button, eg. as on and off the Sunset function. Thus, the alarm is stopped, but is still activated for the next day)
