The white portable doorbell with the gray speaker measures about 13cm x 9cm x 5cm (HxWxD). This inconspicuous optics portable doorbell can be almost anywhere. The volume can be adjusted continuously. The loudest setting the doorbell is heard above two floors.
The structure of the wireless doorbell system designed thanks to a short illustrated instructions as easily. Positive to mention is, furthermore, that the door handle lights up when you press the doorbell. So is signaled to the outside world that the bell works.
A tip: When you insert the battery the door handle (included) you should set the same ring tone. For this purpose, a little buttons located inside the door handle. The manual calls for setting the ring tone until the fourth step. The (thanks to IP44) somewhat stiff housing must therefore not be opened again.
Overall, the wireless doorbell system can be recommended by Byron. For a relatively narrow money you get a reliable, thoughtful and quickly installed bell for the side entrance.
