Contrary to a comment it is not silent but almost silent. Personally I understand to 2.80 meters. But nothing in the product description says it is fully silencieuse.Pour his defense is not an annoying ticking we hear a small but continuous noise that is relatively bearable. Better still do not put close to a bed or a place where you read if you are sensitive to noise.
It is at the time: I set my computer and she took no delay or advance.
