SURFOU M9 Wireless Doorbell: 1300ft long range
Available Options
Meet the SURFOU Wireless Doorbell—your new best friend for keeping tabs on who's at the door, whether you're at home or buried in paperwork at the office. This little powerhouse boasts a 1300ft range, so even if your place is sprawling, you'll hear that knock (or, let's be honest, the delivery guy dropping off yet another package). And with 55 ringtones to choose from (because why settle for boring?) and volume levels that go from whisper-quiet to 'can't ignore this' (up to 110 dB), you can make it truly yours.
Built like a tank with an IP55 waterproof rating, it laughs in the face of Mother Nature, handling everything from freezing winters to scorching summers (-22°F to 158°F, no sweat). Plus, it's got an LED flash for those who prefer visual alerts, and a memory function that remembers your settings like your favorite barista remembers your coffee order—even after the power goes out.
Setting it up? Easier than assembling flat-pack furniture. Stick it on with the included double-sided tape or screw it in if you're feeling fancy. And with a battery that lasts 1-3 years, you'll forget it even needs one until way down the line.
