Bought one when it first came out since the original/larger model was too wide for our door. Works well, love the HomeKit integration with Siri. Only (large) problem is the battery life: I only get 5-6 weeks on a set of the specialty CR123 batteries, and they're not exactly cheap. By my estimate, I'm going to spend $25-30/year on battery changes. My unit is in the same room as the main mesh WiFi node, and in the same room as the HomeKit HomePod. The recommendations from August was to get the Connect bridge to decrease the WiFi usage, but I don't want to spend that amount of money on a "possible" improved battery life when it won't improve the currently working features.
