Kidde Fire Sentry Battery Operated 4-inch Smoke Detector, with 85 decibel alarm, 2 pack

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. 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.

These little smoke detectors are truly a great bargain! I purchused 8 and plan on getting more, they are small and easy to hang. They come already with batteries so no,having to go back,out cause they dint come with them. These are a great price for safety for your home!

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.

This detector replaced a 10-year old detector, also from Kidde, which had passed it's prime and needed to be replaced. I think the decision by Kidde to go to a smaller form factor was unfortunate. It necessitated replacing the mounting bracket on the ceiling with a new, smaller one. This left the old screw holes exposed and created an unsightly mess. What prompted the decision to miniturize the detector? What was wrong with the original form factor. OK, maybe the technology had improved, but the improved tech chould have been incorporated in the same sized package.

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!!!

false triggering 24hrs after installation. Replaced the batteries. Same thing. Removed and old detector and replaced with "newer is better" big mistake!

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

I did not receive the smoke detector at all and the driver did not give me a receipt for my items therefore we have a problem I hope you all contact me ASAP thank you
