Simple old school detector at a great price.
Simple old school detector at a great price. I got two more for other areas of the house. There's no fiddling with apps or settings, no wifi required. A couple screws to install the mounting bracket, add the included battery and twist into place = DONE.
Thank you for sharing your feedback! We love seeing that our products work great for you!

New smoke detector
It was easy to install and now I can rest in peace and confidence knowing I replaced my old one, it was chirping letting me know it was time to replace.

I love Walmart delivery but I think you should reconsider your shipping options. I had an order which included cotton balls. The cotton balls were unavailable and the shipping option was available. The cost of shipping that couldn't possibly be cost effective. This is one of the reasons prices keep rising.
