Review on BRK SC7010BV First Alert Hardwired Photoelectric Smoke and CO Detector with Voice Alerts by Matt Heringer

DO NOT BUY THESE ALARM CLOCKS. I bought eight of these. Four hundred dollars worthless junk. Constant false positives and the company doesn't even know their own products. Your tech support is directly contradicting the instructions for my smoke alarm. All I needed was my wife to turn off the switch, pull on everyone's ceiling, and pull out the battery because it kept interfering. Their tech support refuses to replace or refund the money. I have a clean house and have tried blowing them out with compressed air. My 5 year old lives in fear of the alarm going off. Revain should pull this product. This is complete garbage and unreliability!
