 For any customers or any of the listeners, your detectors will only last for 10 years, whether they're beeping or not. We're able to tell free of charge. We'll go into your home. We'll check and see if your detector is expired. We'll see if it's a photoelectric or an ionization. So I'm a firm believer, and I'll say it on air, I think every home should be sprinkled, Mike. I don't disagree.
