Bests & Worsts Reviews from Amazon

Had for 6 months no problems then got text notification at 5am, while on vacation 2 hours away, about smoke, then smoke decreasing. Had a friend check for fire thank goodness nothing (truly kind person to go to my place at 6am!) and no more false alarms until the first night home, exhausted , 2AM full blown fire alarm twice. So two major false alarms in one week, read about opening and dusting every month as a possible solution - nope. 3rd gen needs to be able to tell you it's a bug or some dust during normal waking hours but until then I am back to the old dumb smoke detector, sigh. Great idea until it fails when you are far away.
