A well priced co monitor
A good quality item, at a very competitive price with Amazon free delivery service. Arrived exactly on the date and time they stated, well packed and the delivery driver was very polite. The item was very easy fix and set up, had it going in only a few minutes. Very pleased with my purchase.

Easy to install
This little device is economical and does the job, it can be moved so as not to be seen, only heard.

Good product, worth the money!
Easy to install, comes with a clear set of instructions to test and set up your alarm (3beeps followed by another 3 beeps followed by 1 beep during test and you will see a green indicator every 30 seconds in Operate Mode). Recommended to test it every week to ensure its in a working condition It can be mounted on a wall or ceiling or can be free standing too. It comes with AA batteries. I would highly recommend to people looking to buy a CO detector. Worth the money . I would say that the safety level is quite high . The packaging was nice as well and easy to open. The noise level is good , loud enough to hear as well. The brightness was not too bright either . It look really nice to look at and works well too.

Great piece of kit
Excellent piece of kit, at a good price. Has more than one signal, the main one of course being the alarm, which results in a flashing red light. When all is well, it simply flashes a green light every 30 seconds. It also has a "memory of CO" function, whereby the red light flashes every 60 seconds if, in the last 24 hours it detected a high level, but apparently not high enough to go full alarm. It runs on two AA batteries, two Duracell versions of which are supplied. Is also nicely designed in attractive beige with rounded corners - where today everything has to be dirge black or grey with sharp edges, so it seems. Supplied with fixing screws and plugs if you want it fixed to a wall.

Safety first
Bought to replace our old unit, which had served us for 10 years. Well made, sturdy and simple to use. Hopefully this will last us for the next 10 years.
