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.
Great service, the items were sent promptly and in excellent condition. I have tested the alarms with real smoke and they work. I have installed 9 of these in my two-storey home and connected them all wirelessly, and I'm pleased to say that they all go off when one is triggered, though some can take a little while longer to trigger (10-15s sometimes, but the measured lag is not greater than 15s and this amount of delay won't affect safety in a real emergency). I feel much safer having these in my home and hopefully they perform if there is ever a real emergency. And hopefully I won't have to replace them for 10 years. Thanks PSL.
Great torch but needs batteries included
