Vine Customer Review of Free Product (What's this?)
I had my doubts about an exorbitantly priced "smart" battery, but I thought I would give it a try, as a Vine reviewer who receives free product to test out.
The very first time I attempted to connect the battery to my iPhone, it failed. As it turned out, this was a harbinger of problems to come, unfortunately. On the second try, the battery did connect properly. I then inserted it into the smoke alarm, and I immediately got an alert on my phone that the smoke alarm was sounding. In fact, it was not, but I disregarded this errant message and did not receive another such message. However, about 30 minutes after inserting the battery into the smoke alarm, we heard the audible "CHIRP" of a smoke alarm with a battery problem. That was nearly the straw that broke my back, but I let it go. Fortunately, we heard no more chirps. I knew the battery was working for each of the first 9 days after I installed it, as the app on my phone indicated the battery was...

Setup was only a teeny bit complicated. I had to use my iPhone to download the app--the iPad couldn't find the app on the App Store.
The App walks you through connecting it to your WIFI and your phone. You should connect the phone and the Roost close to the smoke detector where it will be installed. I first tried sitting at my dining room table, 30 feet from my router and about 15 feet from the smoke detector, and it wasn't getting enough WIFI to connect. Once I was standing almost underneath the detector, it worked fine. You don't want to do this while you're standing on a ladder, either. Barking dogs and chatty children/spouses should be moved out of the area while the phone imitates a 2400 baud modem (the memories...) to link with the battery.
Husband removed the First Alert 9120B detector from the ceiling in our great room and installed the Roost battery. He had some issues squeezing it into the battery compartment, but between wiggling, filing a teeny bit of...
I installed a Roost Smart Battery 5 days ago. Now, my iPhone displays the battery is "Offline." The Customer Support page on the manufacturer's website doesn't offer any information about this problem. To make matter worse, the Smoke/CO detector that contains this brand new Roost battery started chirping. Update: I removed the "Offline" Roost batteryfrom the Smoke/CO detector and replaced it with a conventional 9 Volt battery. Several minutes later, the disconnected Roost battery started emitting a low beep, approximately every 5 minutes. Interesting how it goes "Offline" when placed in the smoke detector and keeps beeping after it is removed and disconnected.
