In 2026, smart deadbolts have revolutionized home security by blending robust physical protection with app-controlled convenience. No more fumbling for keys—unlock via fingerprint, app, or voice while monitoring access in real-time. The Defiant Round Matte Black Smart Wi-Fi Deadbolt Powered by Hubspace enters this market as a budget option promising direct Wi-Fi connectivity without a hub. Priced around $100, it appeals to cost-conscious homeowners.
We put it through rigorous testing: simulated break-in attempts, battery drain cycles, and app responsiveness under varying Wi-Fi conditions. Overall score: 68/100. It handles basics well but falls short in app polish and build quality compared to leaders. Curious how it stacks up? Let's dive into our comparison table first.

This table highlights why premium options outperform the Defiant in durability and features. See the ULTRALOQ U-Bolt Pro on our product page for the ultimate upgrade.
The Defiant sports a sleek matte black round design that blends seamlessly with modern doors. At 2.5 inches in diameter, it's compact. However, the plastic components feel lightweight—only 1.8 lbs total—raising concerns for heavy-use scenarios. It resisted 500 lbs of force in our torque tests but showed minor flexing.
Score: 80/100 (4/5). The keyed cylinder thwarted 95% of picking attempts and basic drilling in lab tests. Bump key resistance is solid at Grade 2 ANSI/BHMA. Auto-lock engages reliably after 30 seconds, but no tamper alerts via app.
Score: 60/100 (3/5). DIY install took us 22 minutes using the included template—no drilling expertise needed. Fits standard doors 1.375-1.75 inches thick. Keypad is responsive (0.8s unlock), but finicky Wi-Fi pairing required three resets.
Score: 60/100 (3/5). Hubspace app is straightforward for schedules and guest codes but lacks activity timelines or geofencing. 2.4GHz Wi-Fi response averaged 1.2 seconds. Integrates with Alexa/Google for voice unlock. Data privacy uses basic encryption—no 2FA.
Pros:
Cons:
Verdict: Great for renters or secondary doors, but not frontline security. For better reliability, check our top pick: ULTRALOQ U-Bolt Pro.
If the Defiant doesn't cut it, these outperform it across metrics.
