How's that for a more modern smoke detector? You can get this black and bold finish with a brightly colored accent in the middle. If red's not your thing, you've got plenty of other options -- blue, yellow, green, you name it.
The Pyrexx PX-1 smoke detector starts at £28 (converts to about $45, AU$60). There's also a model called the PX-1C that adds in Wi-Fi smarts and sells for £83 ($130, AU$170). Pyrexx isn't selling the things in the US just yet, but says that international expansion is in the cards.
