Does what it should - Update: 03/27/2015

The price / performance of the device is top. The flood has so far worked flawlessly (in operation since 3 weeks).
The light intensity is very good, I would confirm the retailer compared with a 100 watt flood light. The light color is (as expected) cold, so it should brighten areas and not create a cozy ambience.

The motion is a bit random (can not precisely align mm), but since it covers a range and not a scope, it's okay.
Because of its low consumption and little imprecise sensitivity settings I have everything set to maximum (sensitivity, duration, etc.). With the result and with regard to the price / quality I am very satisfied.
I would buy the when required again and forgive therefore a perfect score.

Now 3 instead of 5 star rating:
1. No uniform quality
2. The value for money, so they took some compromises in buying, now is no longer true with the price increase of originally. 15.95 to 18.95 now.
