Hassle free, showed up quickly and easy to install. 5 year old was very happy to have new smoke alarms in the house after learning all about fire safety at school.
Bought this as a knife for opening and cutting down boxes at work but I've ended up using it for so much more. Incredibly sharp and small. Great little package
I have installed 10 of these smoke detectors in my home. I am a retired building services consultant and have designed many fire detector installations. As required by code the detectors had to have a 10 year battery life and be interconnected. These wireless detectors meet the code without the expense of installing fixed power wiring and interconnecting wiring. They are simple to install.
