I want to get into racquetball, what do I need to get started? Price estimates would be nice.
Most smoke alarms only have a life expectancy of 2 to 3 years. If replacing the batteries doesn't work then you will need to replace the alarm. I am going through this as I have already replaced 3 in my home. If you only have the smoke detectors then it won't cost that much to replace them as they go out. Mine are for smoke, fire and carbon and are hard wired into my home. These run me 60 for one.
