on sale for $14.

These normally retail for about $50-$60. They stick out less than an inch
from your wall - very nice looking for a smoke detector. No batteries -
unit has an internal rechargeable battery that lasts for 10 years (which is
the expected life of any smoke alarm).
You need to have a square, round, or octagonal outlet box in the wall -
single-gang outlets are too small for this.
On Amazon back order for 3-6 weeks. Other retailers have them available now
but you have to pay shipping.
