It's okay quun smoke detector, but:
1) It SPEAK you
yes, BEEP BEEP BEEP more but true voice to tell you what's wrong
2) it makes lamp !!!!!
A small snack at midnight in the kitchen, no problem your buddy ceiling will help you get Completion fridge, his is a friend
3) it follows you on your smartphone, and tells you what's going on at home, it can even if you turn off the thermostat nest boiler for safety,
4) it does not consume battery quune per year (for the stack view), and if you can obtain the version directly plugged into your electrical system.
5) it makes you pretty color, green is good and red all (that goes without saying) I smell burning.
I always say that a law should exist to ensure that manufacturers make lousy stuff that we use resources for nothing, if that were the case, the smoke detector would have passed with flying colors,
Quen not forget the smoke detector in March will be necessary, but reassure you, if you nen not, your insurance will reimburse you anyway in case of fire, its purpose is primarily you were sleeping, and CO (odorless) to do its work while you sleep.
If this review helped you thank you noted, if not to put a thank you note, and I would correct what is wrong.
