Title: Wish I could get just CO easier
Review: I know these folks make a One-Link that is just CO, but they're not readily available and more expensive than this unit, It fundamentally bothers me to have a combo unit, as best placing for CO is like 3-4 feet above floor and best placing for smoke is at ceiling level. Still, though, this is a good unit at a good price, and the One-Link system works fine.
