It should have been made clearer that this model needed to be mounted
I sold my house and had to provide one
Great product for a great price
I had one of these carbon monoxide detectors for many years. It suddenly stopped working. It served me well for a long time so I looked for a replacement and found an exact replacement, same make and model, so I'm sure it will serve me well for many years to come also. I love the fact that I can order products on Walmart.com then pick up at the store to save shipping costs and also that "if" I do have to return or exchange something I can just take it back to the store to make my return/exchange without having to "ship" it back to a company.
This product is great for placement exactly where you need it. We had a new gas waterheater installed to replace an existing electric. Being that it is gas I felt the need to have this item installed so that if there ever were a problem with the waterheater we would know. I was able to install it in the room right where I wanted it without having to worry about cord placement, etc. Highly recommend.
it is now a law that you must have a carbon monoxide detector, and if it wasn't you would be very foolish not to have them in your home. it was very easy to install, and it was very helpful that the detector came with the batteries including. it was very easy to shop Walmart Online and will be doing it again
I bought this detector for my antique car which I suspected was getting some exhaust in the cabin. The possibility of carbon monoxide inside the car worried me. Sure enough when we got the car out on the open road the alarm went off! So now we are having a mechanic look into the possibility an an exhaust leak. So this device works and it is a good value.
This is a great carbon monoxide detector-- reasonably priced, great design, not too large or too small. Would recommend.
Perfect - plugs into wall outlet.
This is a small, unobtrusive detector. I just purchased two - one for upstairs and one for downstairs. The fit nicely above the thermostats and look like they belong there. We had to put them in when we were having our home appraised. The appraiser accepted them without question so I guess they "fill the bill" for passing state guidelines.
Great price and easy to install
If you have a fireplace or gas appliances in your home, you should have this product. I have peace of mind now knowing I have a Carbon Monoxide Detector in the home. Easy to hang. Follow instructions about where to place it.
Very pleased with this product and happoy it takes AA batteries, them square 9 volt ones are annoying. The installation was very easy and it came with plastic screw anchors with correct drill bit size info. Also it had a paper stencil to use as a guide for hole spacing. Installed easily, straight and perfectly the first try. Easy peasey lemon squeezy.
The installation instructions include a statement and a template showing the attachment screws are spaced 2.5" apart. After I made the holes in my wall I realized that they are actually further apart than that (more like 4"). That meant I had to redo one of them to get the alarm onto the wall. This alarm was a replacement for another brand that blinked once a minute to show that it was working. This one does not blink and only shows it is functional after the alarm-test button is pressed. The instructions do not state clearly that after 7 years the alarm is at the end of its life and will not detect CO anymore. Other brands also fail at "end of life" but their instructions make that more obvious (all CO alarms are designed to need replacement after that time).
Does the job just fine.
The First Alert C400 was purchased to replace one that was about six years old. The new one looked identical online but the mounting dimensions were different, so I had to reset the wall screws (a little wider then the original). Otherwise, the new unit is fine.
I purchased this unit. Battery unit is poorly designed, battery does not seat properly. Battery cover is hard to open and close. With the battery in place, I pressed the test reset button for testing and the button fell in side. it was either broken or the design is bad that as soon as you try to press it , it comes off and falls down inside the detector. I returned the unit and bought different brand.
This is a good basic unit. I purchased three of these for for installation in a summer home.
Purchased this for the garage. Using a propane heater to heat with while I'm working out there.
very good price for a well brand name.
