Bests & Worsts Reviews from Amazon

DO NOT BUY THESE ALARMS. I bought eight of them. Four hundred dollars of useless trash. Constant false alarms and company doesn't even know their own products. Their tech support directly contradicts the instructions for my smoke alarm. I just had to have my wife turn off the breaker and yank every one of these of the ceiling and take the battery out because it kept alarming. Their tech support refuse to replace or refund. I have a clean house and I've tried blowing these out with canned air. My five year old lives in fear of the alarms going off. Amazon should pull this product. It is absolute trash and unreliable!!
