Customers find the smoke detectors easy to set up and install, with clear instructions, and appreciate their interconnected functionality and safety features. The 10-year battery life receives mixed reviews – while some praise it, others report short battery life and non-replaceable batteries that fail after two months. The alarm noise level is also mixed, with some finding it very loud while others say it’s not loud enough. The mounting system receives criticism, with one customer noting that the mounting plate doesn’t have pre-drilled holes.
