Leeo is for people who don't see a need to replace their existing smoke/CO detectors and just want some peace of mind when they're away, but the pets aren't. I bought one used for $70 because I think it definitely has a place in a "smart"/monitored home. Just like dropcam. Heck, dropcam should be able to listen for your smoke detector. Might justify some of its cost.
