SimpliSafe Smoke & Carbon Monoxide Detector, Battery Powered, 1 Count

Fantastic product, easy installation.

Pairs seamlessly with the rest of the system. I inadvertently tested this on Thanksgiving when I spilled some turkey juice in the bottom of the oven and smoked out the house. I was both embarrassed and pleasantly surprised when I received a call from SimpliSafe to verify my safety. They were able to put a temporary bypass on the smoke detector contacting them

All smoke and CO detectors fail evetually. They have a limited lifespan and I wouldn't trust any that are more than 10 years old.I recently bought 5 Simplisafe smoke detectors and one of them failed within a few weeks.So, why the 5-star rating?I've had plenty of these devices from other companies go belly-up prematurely, so I'm not too surprised that a Simplisafe one failed. Fortunately, I have a premium subscription to the Simplisafe service, and that entitles you to a lifetime warranty on all their devices. I contacted the company and - after some troubleshooting and testing - they sent me a new replacement unit free of charge. I just have to mail them back the defective smoke detector. They pay the postage.Hardware is hardware, and any electronic device may die. Simplisafe probably uses the same manufacturers as other companies, but if you have their excellent premium alarm coverage at least you don't have to worry about paying for device failures.Highly recommended if you have a premium Simplisafe plan already. BTW, it's a great service.

These work well. Thankfully, I haven’t had an actual emergency and I hope to never actually needing them, but I did have a false alarm. That may sound annoying, but it taught me that SimpliSafe will call you IMMEDIATELY. They were very proactive so I feel safe. It was also incredibly easy to install at a reasonable price.

So far, so good. It was easy to install two of these. I hope they work.I installed these to replace X-Sense smoke and carbon monoxide detectors I purchased from Amazon just over 5 years ago. Those detectors regularly passed the self-test when I pushed the button on them. But they never sounded over 5 years, despite a few episodes of very smoky cooking. This made me suspicious and so I did some investigating. I found, yesterday, that Amazon was asked to quit selling X-Sense smoke alarms because the brand apparently let their UL or Intertek certification lapse. Amazon complied by discontinuing sales of the X-Sense detector. Note: The X-Sense detectors I bought 5 years ago did have an Intertek logo on the back. But I lost confidence in the brand based on the reported lapse of certification and my experience of having no alarms triggered in some smoky conditions over the last 5 years.

A little background. I am a paramedic and have over a decade of experience in Fire/EMS services here in the US.I will be keeping this product, but purchasing another CO alarm. I believe everybody should do the same. This product fully functions as expected of a smoke alarm, but I cannot endorse it as a CO alarm.This product will only alarm at a CO detection value of 400ppm. For reference, the area around a furnace is roughly 20ppm normally and safe 8hr TWA is like 35ppm. The NIOSH recommends leaving an area at 100ppm and at 200ppm 30-45min of exposure causes nausea, vomiting, dizziness, fatigue, and can be fatal after hours of exposure. I have cared for patients who have died from a few hours of 300ppm exposure.Now I wonder if they had CO alarms that didn’t even alarm, since alarms that only alarm at 400ppm are legal.What does this all mean? This smoke detector/CO alarm combo is perfectly suitable for smoke protection, but is not ideal as a CO alarm solution. Because it takes a medium-high range to alarm, steady but dangerous lower level exposure can go unnoticed.Otherwise, the product works will with the SimpliSafe system, it was easy to install, and easy to mount.UPDATE!After contacting the support team I was informed product will alarm at ranges: it alarms at 70ppm after 1-4hrs and at 150ppm within 10-50min. Which is better. The information is on a separate CO flyer, which was not present in the boxes. So I have amended my review to 4 stars, but while better I personally would prefer to know a little sooner.

This is a worthwhile addition to my simplisafe system, which I've had for about 15 years. Excellent products, excellent company, and excellent customer service. I have a gas furnace and water heater within 5 feet of each other so I placed this on the ceiling between the two. The instructions were clear, not only how to install it, but to set it up so my app, which lists all of the other items in my system now shows the condition of the batteries, and whether they're on or off for all my SimpliSafe products.

My son demanded that I get one of these for their accuracy, Quality, and safety, we wound up getting 2.
