Product Cons

• Limitations of Ionization Smoke Sensor: Uses an ionization-type smoke sensor, which may have inferior early detection capability for smoldering fires compared to photoelectric sensors, presenting a potential performance weakness. (Inferred based on similar product experience)
• Inconsistent Product Lifespan & Alarm Chirp: Customer feedback indicates varied product lifespan (3-10 years), and frequent or abnormal 'chirping' issues severely impact user experience and product trust.
• Lacks Modern Smart Features: As a product launched in 2008, it lacks integrated smart home features like Wi-Fi, app control, and voice prompts, creating a generational gap with emerging competitors. (Inferred based on similar product experience)
• Inconsistent Warranty Information: The product page (bullet points and long description) contains conflicting descriptions of the warranty period ('10-year' vs. '7-year'), potentially causing customer confusion and distrust.
• Low Flexibility of Wired Installation: Inherently requires hardwired power connection; although it has battery backup, compared to purely battery-operated models, it presents higher installation barriers and limitations for locations without pre-existing wiring or for renters.
