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.

First Alert CO511B Wireless Interconnect carbon monoxide detectors work just fine..
I thought linking the two alarms would be a challenge but it proved to be relatively simple. Setting the location the alarm was even easier.I do have but two minor complaints about the product, a) the ready light only blinks dimly once every minute instead of being on constantly. If you don't want to use the test button you have to stand and wait. b) Since I live in a smallish 3 story home the warning alarm with location voice alert is VERY loud ,which is probably not a bad thing, but when first tested it scared the neighbors also.I have two and within my small house they are adequate to alert the entire house. Did I mention LOUD
