I installed in the house a total of 8 of these smoke detectors. The Merten Argus detectors offer as opposed to the construction market products a great look, thanks to which you can hang on the ceiling in the living room without hesitation, the detectors also. The idea of the Long Life Battery is also great, as the extra cost compared to the standard model so quickly counted and not you have to walk through the entire house after a few years to change the batteries. To date, all detectors functioned without problems. However, recently the first detector triggered during the night out for no apparent reason. This behavior I had after some time also at the hardware store detectors, hoping by the lush More price of Merten detector here these problems no longer have to. False alarm should remain an individual case, then I would also be awarded 5 stars, as remains worried to be again sometime ripped in the night without reason from the sleep. I will update the review, should the behavior occurs repeatedly.
Update: After more than a year and 8 detectors in operation, it remained to date in which a false alarm, so I forgive again the 5 star. Visually I like the smoke detector to be very good, much better than the cheaper offshoot.
