Data from Amazon and official Aqara and SwitchBot sites.
2026 verdict
SwitchBot Lock Ultra Vision Combo wins on price, rating, battery life, integrations, unlock methods and emergency fingerprint. The bundle costs less, reviews better, runs about 9 months per charge versus 6, includes native support for every platform including IFTTT thanks to its included hub, and its Keypad Vision adds 3D face recognition to fingerprint, passcode, NFC, Apple Home Key and app entry, with an emergency fingerprint mode on top. Aqara Smart Lock U400 answers with an IP65-rated outer panel the indoor-only SwitchBot cannot match and its UWB ultra-wideband unlocking that opens the door as you approach with an iPhone or Apple Watch. Both offer full guest password features and Matter support. As a complete package, the SwitchBot Lock Ultra Vision Combo takes the win; exposed doors and UWB fans lean Aqara.
