I prefer a detector that is easy to maintain. I check how often the batteries need replacement, whether the sensor has an expiration date, and how simple it is to test the unit. In my experience, regular testing is essential, and I like detectors with a test button that works quickly and reliably.
Best Placement in My Home
Before buying, I think about where I will place the detector. I usually want one near sleeping areas, and sometimes another near fuel-burning appliances if needed. A battery powered detector gives me flexibility because I can install it in more places without worrying about nearby outlets.
