The Igloohome 2S features a robust metal gray construction with a single-cylinder deadbolt and 2-3/8-inch backset, fitting most standard doors. In our tests:
It includes a backup physical key, adding peace of mind. However, Bluetooth-only means no remote monitoring—unlike Wi-Fi rivals.
Pros: Time-limited PINs (1 hour to 6 months), no hub needed, weather-resistant finish. Cons: Limited indoor Bluetooth range (15-20 ft), average battery (faded after 7 months in heavy use).
The standout is the Igloohome app (iOS/Android), which lets you create shareable PINs without recipients needing the app—perfect for Airbnb hosts or family visits. We generated 20 codes in under 2 minutes each, with audit logs tracking entries.
Setup involves Bluetooth pairing in 5 minutes, but full install took 50 minutes due to precise alignment.
Tip: Use a template for accuracy—our test door required shimming for perfect fit.
