Just changed my mind on wireless sensors after one job in a 1920s house

I used to turn down any job that needed wireless contacts, swore they were nothing but battery calls and false alarms. Last week I picked up a panel swap in a brick house near downtown Boise, no attic access, plaster walls, zero fishable runs, so I quoted a full wireless kit just to get in and out in one day. Six days later the owner called, not about a fault, but to say her cat set off the motion twice, and I ended up relocating it for free because I mounted it right across from a heat vent like a rookie. Turns out my gripe was never the tech, it was me skipping the walk test and rushing placement. Anyone got a sensor brand that holds its battery claim past two years, or am I still dreaming?
