Kidde 5CO Carbon Monoxide Alarm and Detector with AA Batteries - 10 Year Sensor Life CO Alarm for Home

Got these 2 items for myself and my family who live in separate places at my home and both have kitchen with boilers nearby. These items are medium-small and can be placed anywhere around the house where it is required and are robust and sturdy and have a good battery life making them last longer. Simple instructions are included. The alarm when toxic carbon monoxide is detected is very loud providing you ample warning and danger of this hidden poisonous gas. Also purchased at an reasonable price for 2 items. Does exactly as advertised and must buy. Better safe than sorry.

The big selling point for me was the 7-year warranty on top of the 10-year sensor life -- for less than £20 this seemed like a great deal when comparing it to the other options on Amazon.Everything you need to get this unit up and running is included in the box. In the package I received were 2 good quality Duracell AA batteries to power the alarm. Also in the box were 2 screws (with wall plugs) for fixing to a wall, a 22-page user guide (quick start on last page), and a rather handy instructional sticker to place somewhere for guidance on what safety steps to take if the alarm goes off.The unit feels sturdy and is compact enough to make it portable (even to take on holiday). It can be placed on any level surface - I have mine on a shelf not far from the central heating system. The front of the unit is very user-friendly with 3 LEDs showing power, fault, and alarm status. The test/reset button is a good size and feels positive when pushed to do the weekly test. Incidentally, the alarm is nice and loud!Overall, I think the Kidde K5CO Carbon Monoxide detector is a great buy and I would highly recommend it if you are looking for something that is super-easy to set up.

This is my second Kidde alarm It is easy to set up and the alarm is a sound you can’t miss! I have a Calor gas fire so need an alarm I can trust Good value and very good quality

I've had this for a while now and it's working fine. Testing is easy, press a button and you get the loud noise and the lights all come on - but most of the time there are no lights showing. Just the green one that flashes every 30 seconds to show it's working normally.

Easy to install and peace of mind when working. Reasonably priced

Very neat and sits nicely on the wall, very good quality and easy to use.Very loud when tested but that’s what you want a sensor to do if it’s needed!!!

Had the item previously+always worked well. So bought this new one+trusting for the same great service!! Easy to install.

Very easy to follow instructions and set up. Good value for money too
