I installed one doorbell outside by my backdoor. The area gets a lot of sunshine and the wall gets quite hot in the summer. It also can get soaked in our crazy rainstorms. This doorbell never seems to mind. Ive had it about 2 years and I love it!There are a lot of sound or ring options. The volume control really gives a nice range. Easy to set the ringtone and twice as easy to install! I use the second loudest setting and I can hear it from my room (65 feet down the hall), but it isnt loud and annoying if youre in the room with the actual unit.I installed the second doorbell in my kids room. Their room is downstairs and when the door is shut they cant hear anything me call for them. I got tired of running up and down the stairs every time I needed their help, so I decided to VonTrapp it! (See The Sound of Music). Now I press the doorbell from my kitchen upstairs and it rings in their room downstairs...a good 40 feet away and through multiple walls. Its awesome! I push a button and they come running! (Anyone who doesnt come within 2 minutes loses electronic time, so theyre well motivated.)Love it! Thanks for a GREAT product!
