• Ordered early in the morning (~ 4AM) and they arrived the same day although they did arrive in two (2) separate shipments. I think as they were coming from actual brick-and-mortar stores they did not have full stock at one as I ordered eight (8) of them • Already had the same brand but without the Co2 and 10-year battery. Got tired of hearing the older ones seemingly start beeping soon after the batteries were replaced. As they were over 10 years old decided it was time to replace

Walmart Was Great

I needed to replace a like kind detector and could not find it at Lowes, Home Depot or Ace. I was amazed Walmart carried it and it was in stock at the local store at a better price than mail orders. It was a relatively simple replacement and to date is working great.

Great replacement for the old unit I had.

Great item replaced one that was 13 years old and was no longer working. 10 year warranty on alarm and battery. One of the great things about this unit is that it has a Lithium battery that last 10 years, no need to replace 9 volt batteries. Easy to install just need to replace the mounting bracket. It plugs right into the existing wiring from the old unit. I like it so much I think I am going to replace the other 4 in my home.
