Bests & Worsts Reviews from Amazon

I just started renting a new home where the landlord has 3 of these detectors installed, one on each level. Today, my roommate and I decided to have a fire in the fireplace, then had to leave to grab something from the store. We extinguished the fire (we thought) and left, only to come back an hour later with the house completely filled with smoke. None of the detectors went off. It turns out the fire was still smoldering when we left, but we had closed the flue because we thought it was completely out. Thankfully there was no damage, just a thick smoke smell throughout the house, and it really was fortunate that we found out this way that the smoke detectors are useless. For some reason, the house being entirely filled with smoke was not enough for the smoke detector to see any cause for alarm. I'm taking down all three detectors and replacing them with photoelectric detectors immediately; according to my research, photoelectric detectors are much less likely to cause false alarms from cooking smoke and are more reliable in detecting all kinds of fires, not just the hot flamey ones. Also, carbon monoxide detectors should have a digital indicator of current CO levels, not just an alarm when the detector decides the levels are dangerous. A malfunctioning alarm could end up not signaling when even the lowest levels of CO are present and end up getting you sick or killed, whereas one with a digital readout will always tell you if there is ANY CO present in the home.
