Review: Bought this smoke detector because, you know, fire safety is important… Apparently not important enough for me to install it in under 90 days. But hey — I had other things to do. Like reorganize the garage. Twice. And stare at it in the box on the kitchen counter like it was going to mount itself. Meanwhile, my wife spent three months walking past it like she was in a house made of dry hay and open flames. Every time the oven turned on, I got the look. You know the one — the “If the toaster sparks, we’re done” look. ⸻ 🔥 Smoke Detector Functionality Once I finally summoned the courage (and a step stool), this thing installed easily and worked like a champ. Tested it with the “toast test” and yep — she’s got lungs. Loud enough to wake the neighbors, the pets, and possibly the dead. I feel safer already. So does my marriage. ⸻ 💵 Value for Money Excellent. A small price to pay for not living in a potential fireball and regaining my wife’s trust. Honestly, I should’ve paid more just for the emotional damage I caused by procrastinating. ⸻ 🧰 Quality & Build Solid construction. Doesn’t feel cheap or flimsy. You can tell it’s built to detect danger, not just hang out on the ceiling for decoration. ⸻ 🔄 Ease of Replacement Swapping it in for the old detector was fast and painless. If only me actually doing it had been that easy. Seriously, it took longer to unwrap it than to install it — once I finally picked up a screwdriver. ⸻ 🧯 Final Thoughts: • Yes, it works great. • Yes, it’s loud, reliable, and makes us feel safe. • No, I can’t explain why it took me a whole fiscal quarter to install it. Wife’s happy. House didn’t burn down. Marriage survived. 10/10 would delay installation again (kidding, honey). Review: I received what I ordered. These have built in batteries with 10 year lifespan, so there is no need to replace batteries every year. I ordered 7 of these and the battery lifespan started within a couple months of my purchase date - I didn't receive anything old. The smoke alarms are all the same and easy to install. They have a third wire to use for networking.
