It is very satisfactory for its price and its use.
It has plenty of sounds and has been used in apartment buildings.

Very good but.. when I unplug it and plug it back in, it makes a noise, so if there is a power outage at night as soon as it comes back on, it will start making noise.

Easy to use, it has been installed approximately 12 meters away from the main entrance of the house and works perfectly

Very good. I bought it for indoor use between 2 houses with a distance of 60 meters between them. My elderly parents needed it to notify us when they needed us. Strong sound, many melodies.

Very good range, very beautiful as a device, many doorbell sounds, unfortunately though with the first rains it filled with water, so we go for something else....

It is one of the best wireless doorbells I have purchased. I have had it for 2 months and it always works perfectly, even after heavy rain
