    great valu

    great product, I just replaced my 11 year old detectors with these that have lithium batteries instead of the 9 v that had to be replaced annualy these plugged right in to the old connectors without rewiring anything very happy with this purchase. I paid $4 more for this 2 pack online than i would have paid for a single identical detector at a local big box store

    good value

    With the 10 year permanent battery they're the obvious choice as hardwired units need to be replaced every 10 years anyway.
