I purchased one of these for my Toyota SUV that has over 400K miles on it. Weve been using these in our airplanes over the years. They used to be the primary CO detector, now we use them as a backup to the CO Detector on the Sentrys. The Toyota still runs good as ever and I like to have this in the cabin with our two year old daughter riding in there now. It gives me peace of mind.

This is a great device, especially in areas where its sometimes too cold for the electronic ones to work. I remember years ago they had similar ones in the school buses. They shipped it first class mail, so the shipping rate was reasonable. Thank you very much Aircraft Spruce and Specialty Co.

good product

Great product in its own sealed packaging so it doesn’t accidentally come open during shipping.

It’s a simple easy to use safety device, to alert you of a silent killer!

I have had these on my Cardinal. Im no longer flying, but put one on my Toyota.

just what I wanted.

Product as shown and described, fast shipping and well packaged. Would buy again.

I use this in addition to having a battery operated Foreflight Sentry CO detector. Just in case the battery dies I then have a simple backup. Make sure you integrate looking at this detector as part of your instrument scan!

Good tool to have in the cockpit.

Great product

As with all products I have purchased from Aircraft Spruce, they are great quality at a very good price. I will keep buying from them.

Twice in my flying experience one of these has saved the day, both times due to an exhaust leak brought in through the cabin heater. Smelled nothing, felt no symptoms, just noticed the dot was turning black. I immediately shut off the heater, opened the cold air vents and landed ASAP. Both times the dot had resumed its normal color by the time I had landed.

Every cockpit should have some sort of carbon monoxide detection.

Great unit thanks

Havent installed yet.

Simple, inexpensive. No immediate alert for spike in CO level.

Doesnt work as quick as the electronic ones, and its sensitive to hot temperatures. For the price though, it does the job.

Product will probably work fine and indicate the presence of CO in the cockpit alright. But as Ive read in other reviews . . . the sticky tape to hold it in place is essentially non-existent.

Why is the sticky pad so ineffective? I was disappointed in that. Otherwise, its a cheap detector, I assume it works as advertised.

Didn’t last 12 mos as expected - good for about 8 mos

Just good for few months 3-4

Never got to use it. The adhesion strip on the back is paper thin almost ensuring it won’t adhere to anything with any wave. They should make this with a padded adhesion strip and it would accept all situations

Great idea, however the double sided tape that comes attached doesnt stick worth SQUAT!!
