Installation follows provided instructions.

Exceptional battery life, much higher service life for a Carbon Monoxide detector, a combination smoke / CO detector, and cumulative CO exposure in PPM is awesome.
10 year battery life is impressive at any price.

Just make sure to note the display alignment is unusual. A misaligned display could be a bummer.

Great deal times 3.

I bought this item because of the high risk of radon in my area. It comes ready to use , great instructions on where to place it, has a reset button so I can move it room to room and easy to read screen. It shows the highs and lows. I love it!!

Great item!

Works well and if you already are replacing a hard wired smoke detector.  You won't have to drill any additional holes because it fits right into your original smoke detector holes.  Just screw in the base, twist on the unit and you're good to go.  Easy install and replacement.  A little pricey, but worth it.

I am extremely pleased with this set of 3. I love not having to replace or fool around with batteries for up to 10 years!  I like the flashes to show a working battery every minute. They were easy to install and started up exactly as the enclosed instructions said they would. A very good bargain to get 3 when I paid more than half of that price for one. Those batteries always died after midnight and would send out a piercing loud siren noise every 10 minutes. You had to get out of bed to address the problem. No more, so happy!!

Happy with this purchase.

Well,  I hope I never have to find out if this product works or not. I hope it does. A relative is coming to visit and will take it outside for a smoke test. 
Alarm looks very nice. Was easy to put together. And very easy to screw to the wall. 70 years old here and did it myself. 
I would recommend it for everyone. Will be getting another one after this smoke test.

Alarm

Two years ago I installed 5 identical units and one recently failed.  This recent purchase was to replace the failed unit.  Despite not lasting 10 years, I went back with the identical unit to allow use of the existing mounting plate and simplify installation.  The remaining 4 original units appear to be operating normally.  I do not know if they will last 10 years.
Overall cost of this unit was less than comparable units by other manufacturers.

Replacement CO/smoke Alarm

The device works very well, is easy to start. However, there is no explanation in French for a product marketed in Canada.

Excellent device but small downside

The advertising for this product is inaccurate and misleading. It is not UL or ETL certified but the advertising states that it is compliant with UL. If you are using these for any type of project that will require government inspection, they will not pass the inspection. I need a refund for my purchase.

Not UL or ETL listed and will not pass inspection

My radon mitigation system has been acting up recently and I hoped this product would give me some data to evaluate my risk. I powered it on a month ago and all seemed well. I checked it a few days later and it seemed to be working. A month passes and today I check it again... flashing display with crazy numbers. I pull the batteries and put them back in.. "ERR 02." I try to power cycle it again.. "ERR 02." What a piece of trash. Never trusting this brand again.

Absolute trash!

Simply put, they don't work.

I've now filled my house with smoke accidentally multiple times and both of these smoke detectors that I have do not work.

They don't work and that is dangerous.
