Works but ... 20

Like many I am the dune wireless doorbell research works at a distance (20m), with obstacles to cross (transmitter behind a pillar cinderblock, chime inside, so behind brick walls). This model seems to work for now.
The problem I noted, however, that the transmitter is not advertised as waterproof ballast. Indeed it has daucun seal at the closure lid. The slightest rain flow along the wall will bring moisture inside. Dailleurs This is the main cause of failure of this kind never Unit-chime itself remains warm inside.
The model i received nest dailleurs not the one shown on the site amazon. The démetteur Case is white, without demonstrating supporting LED on the button (although utilie whether the signal is issued) and seamless détanchéité. Nothing on the packaging / notice nindique dailleurs that the transmitter is waterproof. Amazon should therefore review the product description.
Finally, there was a week before my order, product detail section on the site showed a rather flattering description the amazon removed .... (?)
So see over time
