Carbon Monoxide Alarm Detector EN 50291 Certified, CO Alarm Detector with Digital Display, Battery Powered, 10 Year Sensor

Not only do the item look good it works very well. Bought it to replace one that was out of date to use. Easy to test easy to use a great item.

Excellent

Easy to install and good price. The display is good. The test switch works. Never had a gas leak, hoping that it stays that way.

Solid model, accidentally put it through the washing machine and it beasted through, alarm going and everything. Had a boiler incident and it alerted me.

This is a well designed compact product with a clear digital readout including room temperature. Installation is simple and quick. The instructions could be better and have lost clarity in translation to English. On the plus side the gas sensor has 10 year life. The alarm requires 3 AA batteries (not included) which need replacing every 18 months. A low battery level indicator will sound. Overall a good value, well priced product.

Nothing much to say about this item, it just does what it is supposed to do. Mounted on the wall it is quite unobtrusive and the batteries seem to last for ages, however, once the log burner is de-commissioned for the summer months I tend to remove the (rechargeable) batteries I use. So far I have only need to recharge them once in the last twelve months. The unit also displays current ambient temperature if you are curious. I hasn't alarmed so far so cannot say if it WILL in an emergency..... we shall see.

Bit hard to tell if its functional unless our boiler starts spewing bad gasses... definitely no signs of CO poisoning and batteries going strong after a number of years now.

Stopped working after 3 years 000ppm

Fácil y sencillo de utilizar. Lo pedí por error, ya que lo que buscaba era un detector de CO2 y no de monóxido de carbono como es éste. Devuelto de inmediato, pero funciona muy bien. Recomendable.

The reason that we ordered it was safety - To be warned if carbon monoxide levels in the atmosphere of our apartment become dangerously high. Carbon monoxide kills! Our central heating boiler maintenance company recommended we should install an alarm system. So we identified this unit on Amazon and ordered it.. The speed with which our order was delivered was impressive! It was simple to install. The system test works as advertised. Seems to have been a good buy.
