Being able to see and hear my little one well while in their room gives me so much peace of mind, especially when transitioning to his crib! It has good range throughout my house. It does keep track of the temperature of his room well — he prefers 68-70 so I can make adjustments before he wakes up! It also doesn’t connect to WiFi and has no log ins, so sitters can use it without needing access to our personal systems.
