Yamiry Smart Knob
Score: 70/100Rankings
The eufy Security Smart Lock C210 is a budget-friendly keyless entry deadbolt with built-in Wi-Fi and a touchscreen keypad, offering five unlock methods and BHMA Grade 3 durability. It lacks biometric scanning and door-sensing capabilities, which are notable trade-offs for advanced users. It is best suited for DIYers wanting quick install and basic remote/keyless access for family or guests.
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.
