These are great!
These are great alarms. All four of them synced together instantly and were very easy to install. They are loud and I particularly like the digital readout. Good product and a good price.

Recommended by a friend.
My friend’s husband recommended this brand as being reliable. He has used them for years. I installed them without a problem and the two units synced easily.

Terrible Product, Terrible Company
I installed 14 of these in my house in 2020. FIVE of them died within four years, and a sixth just died on me. TONS of false alarms. Batteries last two or three years. I've had it. I'm ripping them all out and replacing them. WAY TOO EXPENSIVE FOR THE VERY SHORT LIFE AND ALL THE NUISANCE ALARMS (especially if you have sleeping babies in the house).

It works well
I used this to replace an older one that had expired. No problem with installation.
