WoW. This was a great price, I revived it fast. Condition, new in original package. It also came with a protective case. I highly recommend.

This is very sensitive and easy to use.  I had a problem where my plumber, who didn't have a gas detector and has a poor sense of smell, could not locate a leak that I was smelling.  I purchased two of these, one for him and one for him, and it only took him a few minutes under my house to pinpoint the leak.  It turned out, a fitting was loose.

This is a replacement for an existing unit at my mom's house. She had a small gas leak & it did alarm, so worth it's weight in gold.
The only thing to be aware of is it will also pick up any kind of aerosol spray, so if you are installing for an elderly parent, be sure & let them know!
Keep in mind your elderly mom/dad might forget to turn things off, so get them one of these.

Very useful for spotting air leaks around doors, windows and recepticles. Very useful and accurate too for the money.

Used for controlling a furnace burner, uses flare fitting so youll need to cut the end off and replace with regular NPT barbed fittings

Safety Siren Pro Series HS71512 3 Radon Gas Detector

I did two measurements. One - with the Safety Siren and one with the standard Radon Test Kit purchased in Home Depot.

The Radon Test Kit was sent to the Lab, and the result was - 4.3pc. The safety Siren gave result - 0.9pc. The error is more than 75%.

I can accept an error for 10%, but not 75%. I am an electrical engineer, and I never seen electrical devices with such precision.

What I have to do now? Could you give me an advice?

Sincerely
Nick

Buyers beware, as of 2017 the Department of Energy placed new standards on BTU calculations. The 10,000 BTU AS ADVERTISED is based on the Ashrae test, not the Dept. of Energy which only tested this product as 6,000 BTU!!! How they get away with selling this product and not violating Federal Trade Commission guidelines is beyond me.

Only smoke detector in which you can change the battery without removing unit from its bracket. Unit works flawlessly.

This is the newer version of the ones I bought years ago.
It was time to dispose of the old ones and get new ones.
You can't keep these forever, you must get new ones (that goes for ALL detectors).
My home will never be without these.

There is NOTHING, on the box, on the units, back of the units, in the manuals, nothing nothing says they are CO detectors as well.

I live in CA where you have to replace your smoke detectors with combo smoke/CO detectors for the city to inspect.  These JUST say they are smoke detectors.

They were made in May of 2013, so not like I got an old box.  Either it's a advertisement and they aren't CO detectors, or they have gone out of their way to mention that exact NOWHERE!

I called the company and while a search for 9120B6CP brings up the manufacturer's page saying the are CO detectors, these are not what is now listed on their site, and are indeed NOT CO detectors.

I needed this specific model to replace a malfunctioning smoke detector. It has been in for several months and has worked fine.

I got these when our CO detector was beeping for no apparent reason, to find out whether there was indeed any CO in the house.  Thankfully, this device indicated no carbon monoxide present.  I later determined that our old detector had reached the end of its service life and replaced it.  These detector buttons should keep for a long time; so I can use them later, anywhere anytime, or as a backup.

Bought this to track down a propane leak in my camper.  Or rather, prove it was a leak in my furnace line since I'd just added that gas line and we were getting propane alarms every night since.  And it turned out, it wasn't that - it was the regulator in the stove, the diaphragm in it had apparently busted and started leaking.  Would have never guessed that without a sensor (or carrying it to a shop/dealer).

Took a while get the hang of this detector but it wasn't that bad once I saw what it was doing.  Let it calibrate for a few minutes in fresh air and then dial the sensitivity down to just past getting rid of the clicks (still in fresh air).  The go find your problem.  Slow repetitive clicks don't necessarily mean anything, there's almost always traces of some kind of gas around (breathe or fart on it and it goes off - confirmed).  You've found your leak when the unit goes crazy.  There's a delay for it to detect, so move slow as you're detecting.  Also had to tinker with the sensitivity since being in a rather confined space with a known gas leak, the whole area was gassed-up so had to dial down to find ground zero.  And once it's detected positive, I found if that didn't lead me to a precise enough location, I had to take it back to fresh air for a minute to let the sensor get back to normal before heading back in.

As usual Amazon had the best price for this product. It arrived in a few days and was exactly as expected. The detector has saved me a few times already, once with KA and the other with laser detection. Good detector for the money.

battery leaked, and fumes permeated our home. the worx representative did not care. Had to call the gas company. I thought we had a leak.
Dangerous product in my opinion. The battery was so hot, I feared an explosion.
