No frills but does the job,
Verified Purchase(What is this?)
This review is from: Honeywell H450EN carbon monoxide detector (DIY & Tools)
This detector was purchased to replace a previous model of the same style which had reached the end of its life. The best thing about this detector, and the reason for purchasing this type again, is that you can comfortably sit it on a shelf or a small ledge and don't need to wall or ceiling mount it. It's small and neat enough not to be intrusive anywhere. No fancy features or anything fussy about it, but it was not purchased for that, just needs to be functional. As long as this model type is available I'd be more than happy to buy further replacements in the future.
