Wireless Indoor/Outdoor Doorbell

I got these for our house when we moved in 4 years ago! I got one for the front door and one for the side. The side door battery just died this summer as it gets used more and the front door one is still going strong! I set a different ring for each door so I know which one and I love that there are so many options to choose from (52!). You can also adjust the volume! These would be great for an apartment/condo!
