Review on 🔥 UL Certified Photoelectric Smoke Alarm Fire Detector, 3-Pack with Light Sound Warning, 9V Battery Included – Powered Fire Safety for Home, Hotel, School and More by Juston Alonso

Received these on December 31st 2018 and quickly installed all three in our 2010 40ft-5. Rad. It caught fire on the evening of January 2, 2019. The fire occurred in the 5th wheel area (bottom/outside) and the smoke detectors on that end never beeped. We tested them afterwards and they did great. There was no flame in the trailer. Just tons of smoke. Never made a sound. I personally cannot recommend this product. Luckily we found the cause of the fire and it wasn't as bad as it could have been. If we had slept in bed we would not have been warned at all. Very creepy.
