Ruiming Wireless Doorbell: RF433 MHz frequency
Ever wished your doorbell could do more than just announce visitors? Well, this wireless doorbell is here to change the game. Running on the RF433 MHz frequency, it's like having a reliable messenger between your door and wherever you are in the house. And guess what? It's USB powered—no fuss, no wires, just plug it in and you're good to go. Plus, there's this nifty bedside call button (because let's face it, getting out of bed is overrated). Whether you're in a library or a lively kitchen, the volume can be adjusted to fit the vibe. And with its smart functionality, missing a visitor is so last year. Oh, and it's dressed in a sleek white design because who says tech can't be stylish?
