Best bank for your buck!	September 11, 2012
Reviewer: Fred B. from Pasadena, CA

I was looking for a replacement for my old BRK 4120. I live in California, so with the new CO detector law that does into effect this year 2011, I got this combo unit. This saves me money because I don't have to add new wiring. I can just use the existing wiring. It's quite simple. Just remove the old alarm, replace the mount adapter, install the new combo, power up, test the unit, and done.
