AVANTEK DB-21 Wireless Doorbell Kit - 1300ft Range, 56 Melodies, Waterproof, 2 Buttons
🎵 56 Melodies & 5 Volume Levels - Who says doorbells have to be boring? Pick from 56 tunes to greet your guests (or scare off the squirrels). And with volume that goes from 'whisper' to 'rock concert' (okay, 115 dB), you'll never miss a visitor—even if you're in the shower.
🌧️ Weatherproof Design - Rain, snow, or a dust storm that would make a tumbleweed jealous? No problem. This doorbell's got an IP55 rating, meaning it laughs in the face of bad weather.
🔋 Long Battery Life - Forget about changing batteries every few months. The built-in lithium battery is the marathon runner of doorbells, keeping up the chimes for up to 3 years.
🏠 Easy Installation - If you can use a screwdriver or peel off a sticker, you're overqualified to install this. Comes with screws and adhesive pads because we know not everyone's handy (or wants to be).
💡 Memory Function - Power outage? No biggie. This doorbell remembers your last melody and volume setting, so it's like nothing ever happened. It's the elephant of doorbells.
🔊 Ultra-Long Range - With a 1300 feet range, you could be at the bottom of your garden, in the attic, or hiding in the shed (we won't judge), and you'll still hear it. Maybe even your neighbors will.
