A compact retrofit smart lock that fits over the inside of an existing deadbolt and connects directly to Wi-Fi without a separate bridge. It installs easily and keeps your keys working, but owner reports over the long run center on battery drain, Wi-Fi drop-outs on some routers and limited out-of-warranty support.

It depends on how you will use it. 55% would buy it again, which means roughly 45% would not. Battery life reported shrinking from months to weeks.
The retrofit design and remote access still impress, but battery changes come around more often than many expect. On some mesh routers the lock keeps dropping its Wi-Fi connection, which drains the batteries even faster.
Battery life reported shrinking from months to weeks. Out-of-warranty support tends to offer discounts rather than fixes.
Worth it for: Renters keeping their existing deadbolt; Iphone users who want auto-unlock; Sharing guest access remotely. Think twice if: Android-first households; Mesh networks without a 2.4ghz option; Owners who hate swapping batteries.

A 2020 review that likes the subtle retrofit design, easy install and no-bridge Wi-Fi, but found auto-unlock unreliable on Android and notes the 2.4GHz-only requirement.
Owners describe August Wi-Fi locks repeatedly dropping off Orbi mesh networks and draining batteries; one fixed it with a separate 2.4GHz-only router.
A small, all-negative set of customer reviews citing shrinking battery life, Wi-Fi failures after updates, bridges failing after about 18 months and support that offers discounts instead of repairs.
