Hosmart UltraSpeak Pro Intercoms Wireless for Home, Two-Way Real-time Intercom Full Duplex Wireless Intercom System for Home Use, Clear Sound House Intercom System for Business with 1200 Feet Range

Seems OK for our outside annexe about 100 ft from the house. Range gets considerably restricted if there are windows

Most of the time, I just want to quickly say something to another room, but having to switch to another channel by holding a button to change it is slow and inconvenient, and then I have to switch back to my own channel (same hold button). To quickly speak with someone we have “talk,” and it's great BUT everybody can hear what you said. Making an actual call is just ridiculous—you might as well use a mobile phone—while your devices should work like walkie-talkies, letting you quickly pass information to someone (and get a reply just as fast).

Buen producto, ya había comprado un par y compré 2 pares más

Excellent Product. No installation required. Works out of box

Muy fácil de configurar solo me falta ver si tienen ese Alcance que dice en una casa de dos pisos desde la cosita a todos los cuartos

Cumple con lo que dice escrito

Amei. Funciona bem. Irei comprar novamente.
