The 14-month battery life seems pretty sweet on this. My Ring battery dies at least a couple times a year it seems (granted it's an older model).

I currently have a eufy deadbolt smart lock (T8503) and it eats batteries like crazy. They are the CR123a batteries so they are not cheap, and I've tried lithium and etc, but no help. Still have to change them multiple times a year (seems like every few months).
Did a search for recent deals on here and see the one here, as well as this one (eufy C220), and wondering which one I should get. Anybody have any thoughts?
