Much better than previous brand

I had a different brand for past 12 years but after 3 units failed over this time, I decided to try a different brand, 1800 doorbell. Worked right out of the box. Picks up deer, coyotes, turkey flocks and autos and trucks. I'm very happy with this unit. I got a receiver for house and garage and one transmitter for drive.
