Score: 70/100Rankings
The ULTRALOQ U-Bolt is a versatile smart deadbolt offering keyless entry via fingerprint, PIN, app, NFC, and voice assistants with Matter-over-Thread compatibility. Its primary trade-off is the potential need for an additional bridge for remote access features. It is best suited for smart home enthusiasts in multi-platform setups seeking keyless convenience without hub clutter.
The Yamiry Smart Door Handle Lock (YR01) is a 5-in-1 keyless entry smart knob designed for DIY installation without extra drilling. It supports multiple unlock methods including fingerprint, keypad, IC cards, smartphone app via Bluetooth, and mechanical keys. The main trade-off is the lack of native Wi-Fi connectivity and potential installation difficulties regarding latch alignment.
