AVANTEK CB-11 Wireless Doorbell - 52 Melodies, 1000ft Range, Waterproof, LED Flash
With 52 Melodies, you're spoiled for choice—pick a chime that's as unique as your front door's personality. Whether it's something classic or a tune that makes the neighbors jealous, we've got you covered.
Need to crank it up or keep it down? The volume's adjustable all the way to a whopping 115 dB (that's louder than your average rock concert, by the way). Perfect for when you're in the backyard or just don't want to scare the cat.
Rain or shine, this gadget's got your back. Rated IP55 Waterproof, it laughs in the face of weather, handling everything from a chilly -4°F to a scorching 140°F. Because Mother Nature can be unpredictable, but your doorbell doesn't have to be.
Got a big place? No problem. The 1000ft Range means you'll hear it whether you're in the basement, the backyard, or hiding in the attic (we won't judge).
Forget about constant battery changes. The included CR2 battery is the little engine that could, lasting up to 3 years. That's right, set it and (almost) forget it.
And for those who prefer a visual heads-up, the LED Flash is like a mini lighthouse for your home—great for the hearing impaired or when you've got your headphones on.
Lastly, the Memory Function is like that friend who remembers how you like your coffee. Even after a power outage, it picks up right where you left off. No fuss, no muss.
