Customer Review

So the function I can - fortunately - so far say nothing.
Pass a test the equipment but repeatedly.

If they would also keep their promised 10 years, I am satisfied. It was important that they do not blink because they hang in the bedroom or in the hallway in front of it.

The units make a quality impression.
