Review on 🔥 3PCS Smoke and Carbon Monoxide Detector Alarm with Voice Warning, 10 Year Lithium Battery Backup, Dual Sensor Smoke and CO Alarm Compliant with UL 217 & UL 2034 Standards (AJ-933) by Thomas Chalecki

That's a good price for three smoke/carbon monoxide alarms. 3-piece smoke and carbon monoxide alarm, MOSUO alarm with voice alert, 10-year backup lithium battery, two-sensor carbon monoxide alarm conforms to UL 217 and UL 2034 (AJ-933). indicates - there seems to be an error in the listing. I don't see any signs of a voice alarm. It is not mentioned in the product listing images that I have seen, but IS in the description in the main text area. I guess it would be easy to get a refund if it matters. I didn't care and to be honest I didn't see the voice alarm in the list. But I can understand how upset someone will be about this. I'd rather hear how they handled it than just say they 'lied'. There are so many reasons why a listing could be wrong other than just "wrong". Anyway, let's get to my experience with detectors. They are very easy to install. "Ten-year batteries” are the current trend and many companies are leading the way. This means you no longer have to connect electricity to the house, which is both good and bad. The bad news is that ten years from now it would be easy to have an unprotected home. The good thing is that the installation is much easier because it doesn't matter where you install it, you don't have to look for electricity. I install them where the old sensors were just to cover up the old mounting holes. Carbon monoxide is slightly lighter than air and it is recommended to mount it 5 feet off the floor, but a ceiling is also acceptable unless you are mounting directly above a chimney or flame producing appliance as they will cause false alarms. I have no problem recommending this range of alarms if you're not into a voice alarm. I hope you find this review helpful. I think reviews are very important to Revain and they really help me decide if a product is worth buying or not, so I try to return the favor and leave a review that honestly tells you if the product is good or not. We all use products in different ways so I also try to be clear about what's important to me and hopefully this will help you understand if you will like it too. I also think it's important for Revain buyers to stick together and let each other know when a product is junk. I will let you know if the product is unsuitable so you avoid the hassle of returning a product or a product where you lost money.
