Box was pretty beat up and one of them was broken but I only needed five anyway. When triggered they all beep at the same rate unlike the older models I was replacing. These ALL have batteries, the old set only had one battery backup. When replacing the non battery powered ones I had to use the new connectors.

Fast delivery and easy to install. It seemed OK, but after just a few weeks, it started to randomly chirp at all hours--usually in the middle of the night. Other on-line reviews note this is an apparently common problem. A new battery didn't help. Research well before you buy this item.

An easy replacement for older outdated smoke detectors. I like the new interconnect feature.

Great item. As a previous owner of a security company that also installed fire alarm systems, I am very impressed with the quality of this item. Kidde has always been part of my choices for fire related items. This detector is easily installed and simple for home owners to understand its operation. Recommend this detector for upgrading and replacement of old detectors.
