Wireless Interconnect Smoke Detector (2-Pack) is rated 4.7 out of 5 by 7.
Rated 4 out of 5 by from Good smoke detector Nice knowing if there is a fire in some other part of the house. Not easy to program.

Rated 5 out of 5 by from Great units easy to install and giving better protection for multiple areas The units were quite easy to program and install for the wireless connection. The video instructions on the CD were good. We have noticed that the unit near the kitchen, does not have the many nuisance alarms that our former unit (of another type) had. In our place, the wireless connection with alarm signals at all units are important, as the garage is under the living quarters. An alarm sounding in the garage would probably not be heard in the bedrooms, if it were not for the wireless connectivity in this system.

Rated 5 out of 5 by from smoke detectors that are linked. We have 4 levels in our home, Great to have detectors that will alert the other three smoke detectors when one is activated.

Rated 5 out of 5 by from Great product!! I love the smoke detector. I purchased 3 packs for 3 bedroom, basement, living room and hallway. I had trouble getting them interconnected, but I finally got to work. They were expensive but they are worth it.

Rated 5 out of 5 by from Good Price I purchased this as a replacement and add on to the system I already have. Wireless interconnect is a nice feature. Home Depot had the best price I could find.

Rated 5 out of 5 by from keeping my Family Save The smoke detectors was easy to program. I know that we will be safe if there was to be a fire in our home,because its loud and is placed in each room of the home. The price wasn't bad because it came in a two pack with a saving of $15 each.

Rated 4 out of 5 by from Installs easily Installs easily and seems to work pretty well. The instructions actually make it seem more complicated than it really is. The alarm is nice and loud, although the talking feature seems more of a gimmick. Somewhat on the pricey side.
