The verdict

Why it scored a 80

At $99.98, the eufy Smart Lock C220 is the under-$100 way to get a fingerprint Wi-Fi deadbolt, and Value leads at 92 with Reliability at 86 and Satisfaction at 86 across 4,200 ratings. Features earn 80 for six unlock methods, built-in Wi-Fi with no bridge, and an app shared with eufy doorbells. Quality sits at 66 because it is BHMA Grade 3, the lowest residential grade, where Schlage and Ultraloq offer Grade 1, and Warranty drags at 55 with one year of coverage. It suits a budget buyer who wants sub-second fingerprint entry and eight-month battery life and accepts basic-grade hardware to get there.
