Good value for the pair Good value for a pair of ten year sealed alarms. The batteries should last the lifetime of the products, so they are fit and forget, apart from periodic dusting and testing. The only potential improvement would be better installation instructions for the CO detector. The smoke alarm has diagrams showing the optimal installation position, whereas the CO detector just has a long description which isn't as easy to interpret.
