A trusted brand I love.

gina March 3, 2026

It was time for me to replace a couple smoke detectors in my house and this two pack did the trick. They are easy to install, they are small so they are discreet looking and this is a brand that I know and trust. In my opinion, you can't go wrong with a Kidde smoke detector. Overall, I am highly satisfied with this product.

Simple old school detector at a great price.

Fidgety November 25, 2025

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.

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.

Small but mighty

ejlow February 2, 2023

Small but mighty. Came with a battery. Put one on each floor, stairway and in each bedroom. It blinks a red light, but not often and it’s subtle. Doesn’t grab your attention when you’re in bed, thank goodness. 8 minute pause button for when you accidentally burn your pizza but don’t want to tame the entire thing down and remove battery to make it shut up then forget to put it back. So highlyyy recommend this smoke detector.

I haven't received them so i just put 3 stars except for speed and on time delivery which is 1 star. FedEx is horrible, especially when the box is packed to heavy. Things almost always arrive broken or leaking. Im disabled and can't lift heavy boxes so i have to take item out one at a time outside of the house so as not to leak all over the floor. I am sure its a tough job, time sensitive and busy rushing to get orders filled. It's about quality and consideration for the customer ordering from home as well as in store. Hopefully there can be better training for packers. FedEx is a whole other kettle of fish! I hate to be complaining, but I'm sure you really want to know the truth. Have a nice day.

Marcia January 3, 2025

first 8 hrs after i put the batteries in it started alarming there is smoke.. i til the batteries out until i can get someone to show me how to use it properly. THIS WAS THE REASON for Purchasing the alarms. my dogs all freak out. (my house was rebuilt 3 years ago due to a bad fire. my house has those alarms that are built in hardwired in few spent approximately $500.00 to have 2 different company's vibe out to fix the alarms.. i can't stand the alarms are so loud, they go off for absolutely NO REASON. NO ONE HERE SMOKES INSIDE THE HOUSE. IS YALL CAN HELP ME FIND SOMEONE TO FIX I WOULD SURE APPRECIATE IT!!!

I didn't know when my order was dropped. So the milk and oj were sitting out side in the heat. Could the delivery person ring the bell and or knock to let me know the order was outside

Bought one and it was great, for about 2 weeks.then failed completely, would not take a charge. Took it back and WAL-MART cheerfully accepted the return. Bought another. From day 1, Auto function doesn't work. It does charge. Need to take this one back.
