SURFOU M9 Waterproof Wireless Doorbell: 1300-ft operating range
Meet the Wireless Doorbell from SURFOU—your new best friend for never missing a knock (or a delivery person sprinting away). It's got a 1300-ft range so you'll hear it from the backyard, and an IP55 waterproof rating because, let's face it, weather happens. Choose from 55 ringtones (because why settle for one?) and tweak the volume across 5 levels—or just hit mute mode when you're done with the world. Plus, there's an LED flash for those days when your ears take a break.
Why you'll love it:
- No wires, no fuss—easy installation means you're set up in minutes.
- Got a mansion? No problem. The expandable system grows with your ego—I mean, home.
- Power outage? Whatever. The memory function keeps your settings safe and sound.
- From freezer burn to desert heat (-22°F to 158°F), this doorbell laughs in the face of extreme temps.
Whether it's your home, classroom, or office (or that secret lair you don't talk about), this doorbell's got your back. Visitors? Consider them announced.
