Review title: 20% fail rate within 1 year
Product review: We purchased 5 units in June 2011. Installation was very easy (the same as most other pre-wired household detectors). 5 units took me about 1 hour.11 months later, we had our first unit go into false alarm mode (fire). The LED indicator blinked about once every 15 seconds (not on their status list). Battery replacement doesn't help.So my questions as a consumer not answered on their web site:1) should I buy another one to replace it?2) should I invest the time, money, and effort to send "the alarm with proof of date of purchase, postage and return postage prepaid" for warranty service?3) what is the chance that the other 4 units in our house will do the same thing in the next 5 years?So, -1 star for product failure, -1 star for the hassle of pursuing their warranty repair (how do I prepay return postage on a box?), -1 star because now I WORRY about reliability of the other units that I count on to let me know when there is a fire or CO risk.
