Review on X Sense Combination Compliant Standards Auto Check by Peter Joseph

There's nothing quite like having all your smoke alarms go off at the same time. Well, not at the same time, but several days apart. And all this at night! Why is this? Anyway, I've been looking online and in stores for new alarm clocks. Replacing five at once is expensive. I found this company and was amazed by the quality and quick response when I asked my many questions. Installs easily. My son smokes MJ and every time he's in his room it gets him going. Other than that, they look great and work well. I recommend not only for the quality but also for the price.
