Absolutely ZERO 2

Carillon useless. Between the chime and the button there is less than 15 meters and the button is attached to the input pole (which is not dailleurs stone and inside is empty): no vital reported. If the button is suspended in a vacuum, it's perfect, remains only to think if we can fix the suspension button with nylon son, hoping that the first fox who want to have fun do without tears pity.
On the site of idk it's cheaper but it's money wasted.

Updated upon contact with the VAS IDK:
explaining that the bell could not be considered truly IP44, I had confirmation by the answer: "Maybe your orientation at the rain front, which causes moisture in the button." The button is outside, like every self-respecting doorbell and being presumed IP44 should be "protected against water projections from all directions" (source wikipedia). Given the strength of the rain can not be regarded as that of a lance with a 6.3mm nozzle (which would justify a x5 class IP) IP44 theoretically should protect a projection of the rain, which n ' is not. Also assume that water could enter through the button is equivalent to admit that he is not at all IP44.
I await their response to my objections. To be continued ...
