## Customer feedback

Customer feedback highlights easy setup, the design and phone notifications, with some reports of reliable background operation. Battery life is a notable concern, including reports of depletion after about four weeks, while connectivity and voice clarity receive mixed comments. For a battery-powered alarm that relies on 2.4 GHz Wi-Fi for app features, these reports make both battery upkeep and dependable network access important considerations. Aggregate ratings lean positive overall, but do not establish performance or explain individual experiences.
