A:Answer Yep. Mine eventually had 3 vertical slits completely through it and stopped working. It gets a LOT of direct sunlight and delivery people ruthlessly crush the button when they press it, so ehhh... I'd say it did ok for 3yr. A lot of rain in late summer to early fall where I'm at, so that's very likely what actually killed it, but it still took a while. Warranty covered it anyway, so now my doorbell looks all shiny and new again. Net gain, really. I just bought another for my mom, regardless of mine wearing down. I say just get an extended warranty and let nature do it's thing.
