Review on SECRUI Wireless Doorbell: Waterproof Mini Doorbell with 1,000ft Range, 5 Volume Levels, Mute Mode, LED Flashing - Black by Nicole Mcleod

After the neighbors had a fire from the doorbell, which was punished, then decided to buy a wireless doorbell. I chose from a large segment, but there were a lot of positive reviews for this, and according to people's reviews, I bought a call. Works at a wireless distance up to 150m. It has a beautiful LED backlight, the call button is made with a touch sensor, 32 sound melodies (the volume level is adjustable). The manufacturer writes that it is also waterproof, but I did not experiment. Operating temperature up to -50C (again, I did not check). Wireless frequency 433 MHz. Operating voltage 100-240V AC. The sound transmission sensor operates on a 220 volt network with a European standard plug connector, can be installed in any outlet at a distance of up to 150m. from the call button (installed in the corridor, the sound is heard in all rooms, but I have such an arrangement of the apartment). The kit includes: call button, sound transmission sensor, double-sided tape, 2 fasteners. Installed on fasteners to prevent theft.
