Review: Good quality - Super easy to set up, very small to fit any space.
Review: An Excellent Decently Priced CO Alarm - I don’t know about the rest of you folks, but I find it really helpful the many QUALITY REVIEWS I read about products on desertcart. That is what keeps me writing well-thought out reviews, as your many QUALITY REVIEWS have been of GREAT BENEFIT to me again & again. Thank you. Now for my Review Of the compact KIDDE CARBON MONOXIDE ALARM that comes with a 7 year warranty. I was quite wary (i.e. unsure) about getting another Carbon Monoxide Alarm, as many reviews of Carbon Monoxide were either EXCELLENT, GLOWING REPORTS or very negative ones. So I decided to read a lot of the Carbon Monoxide Alarm Reviews and ANALYSE the results. (i.e. break down my understanding of what they all meant) The KIDDE Carbon Monoxide Alarm seemed to get a mix of both positive and negative feedback. However, having carefully considered its feedback, I decided it was worth considering. The Compact KIDDE CARBON MONOXIDE Alarm is indeed very compact weighing approx 200g (0.44 ounces) and its dimensions being Width * Length * Thickness ➡️ 7 * 12 * 3 cm ➡️ 2.76 * 4.72 * 1.18 inches. It hardly takes up any space and although it comes with screws to affix it on a wall or ceiling, it has a ready-made slot on the back of the alarm to enable you to hang it on a hook or nail that’s partly recessed into a wall. The Carbon Monoxide Alarm comes with instructions and Three “AA“ Size Batteries. It’s really easy to remove the cover to the battery compartment on the back of the Alarm. You just gently slide it down in the direction of the arrow and then put in the 3 * AA Batteries and then slide the compartment cover back on carefully. It’s important to note of course that it’s the actual Alarm Unit that comes with the 7 Year Warranty and NOT the batteries! You’ll probably need to change the batteries once every 7months to a year depending on HOW OFTEN the Carbon Monoxide Alarm sounds. [I say this as I’ve had a few KIDDE Carbon Monoxide Alarms in the past with at least two at any one time. Also, I believe that after about 5.5years or so, depending on HOW FREQUENTLY the Alarm goes off to alert you, the unit will need to be replaced as the CO Sensor inside the unit stops working!]. And VERY IMPORTANT: WHEN YOU FIRST PUT IN THE BATTERIES, THE CARBON MONOXIDE ALARM MAKES TEN RAPID BEEPS, WHICH STARTLED ME A BIT. I should have read the instructions that came with the unit more carefully. You’re also advised to write in the date ON THE BACK OF THE UNIT, the date you installed the Carbon Monoxide Alarm & the batteries, as both the Unit and the batteries have a LIMITED LIFE SPAN. I installed mine on Sunday 26 July 2020 and wrote that date on the Carbon Monoxide Unit. I think it would be easier to write down the installation date with a marker pen. AND REMEMBER to TEST the unit AT LEAST once a week and PREPARE for the loud 85 Decibel Screeching Sound. Some Carbon Monoxide Alarm Units require you to vacuum their insides once every two to three months. I LIKE IT THAT THIS UNIT DOES NOT APPEAR TO REQUIRE THIS! Some people have complained about their own Carbon Monoxide Alarms received being manufactured a few years before they received them. The two I received were MANUFACTURED ON NOVEMBER 9 2019. Thanks for Reading and Hope you’ve Found MY REVIEW HELPFUL...

## Questions & Answers

**Q: Does this alarm emit a loug sound if it detects carbon monoxide, or does it just rely on flashing lights?**
A: You get the full shebang! It emits a loud, high pitched, intermittent bleep and flashes red (test it with the test button. It's that easy folks ;-). An entertainment centre in itself - worth stopping in for!!

**Q: can you change the battery yourself ..**
A: Hi Alan. Yes its very easy to replace the batteries yourself. Just as easy as replacing the one in a battery operated smoke detector. At the back of the unit, an easy opened door exposes the 3 AA Batteries. The unit is Guaranteed for 7 years but this does not apply to the batteries of course.ThanksBrian

**Q: I understand that these alarms have a replace by date - how can I find out what the date is for this alarm?**
A: They either come with a replace by date or a label where you can write the date of installation. The product tells you how long it lasts for

**Q: can the alarm be free standing?**
A: I have it free standing on my shelf in my bedroom and works well.

### ⭐⭐⭐⭐ Life Saver Carbon Monoxide Alarm
*by P***H on 9 August 2018*

The Life Saver carbon monoxide alarm is a relatively small, portable device which comes with a detachable fixing bracket, and 3 AA batteries. This is my second unit as I discovered last week that they have a 7 year life then need replacing. Whilst I am not pleased that these do need to be replaced, they are a vital piece of equipment if you have a gas boiler or any gas equipment in the home or office. This is excellent value and I hope I never have a need for it, but it's absolutely essential.
