I have this for a doorbell. It is wonderful with beautiful sounds. I have set it to play the Titanic when someone rings the bell. The only downside is that I had to stick it to the wall with silicone. It doesn't have a sticker. I use it for the front doorbell and not for indoor use.

Owner of the product and it worked fine for 3 months.
Good range, low sound (it needs to be placed in a central location in the house to be heard well. If you have closed doors, it is difficult to hear).
Without anything happening (getting wet, falling down) and with a new battery.
Unfortunately, it keeps hitting by itself and I will change it.
I was not satisfied.

Easy installation even for someone unfamiliar, strong bell, good range, does the job perfectly

Classic, like most products, as soon as someone buys it, they immediately comment that it is perfect! From the first day of use, it doesn't hit on the first try, someone has to press the button a second time! I had bought a Legrant for 15€ that always hits, I just wanted a second one for the other entrance of my house.

Very powerful sound, instant activation, many tones of ringing. So far, it works perfectly without any problems. I use it in the bathroom to notify me when someone needs assistance.
