AVANTEK CW-21 Mini Waterproof Wireless Doorbell: 1,000 ft ultra long wireless range
Looking to give your home's entrance a little upgrade? Meet the AVANTEK CW-21 Wireless Doorbell—where practicality meets ease in a way that actually makes sense. Imagine this: a doorbell that doesn't just whisper but actually reaches you from up to 1,000 feet away, because let's face it, we're not all camped out by the front door. And with 52 melodies to pick from, you can finally ditch that boring 'ding-dong' for something with a bit more personality. Oh, and it's got an IP55 waterproof rating, so a little rain (or a lot) won't stop it from doing its thing.
But wait, there's more (and no, we're not just saying that). The CW-21 is smart enough to remember your favorite settings, thanks to its memory function—because who has time to reset things after a power outage? Plus, it comes with two transmitters, each singing their own unique tone, so you'll know whether it's the front door or the back without even looking. And despite packing all these features, it's got a compact size that won't hog your outlet space. Perfect for homes, offices, or even that one classroom that still uses a doorbell for some reason. The AVANTEK CW-21: reliable, stylish, and surprisingly not annoying.
