This unit is small, inexpensive, and easy to install. Our gas company tested it and it works very well. The alarm could be a little louder but other than that I have to say it does the job of units costing three times as much and there is no wiring or difficult installation requirements. Just plug it in and it is working. Doesn't get much easier than that.

I was disappointed to find that this U.S. manufacturer is actually
selling gas alarms that don't address current safety standards.
Specifically, I found that the product manual does not say it is
UL-listed for any relevant Underwriters Laboratories standards, and
when I checked the UL product database I could not find listings for
this product for either explosive gas (UL 1484) or carbon monoxide (UL
2034).

In the case of explosive gas (UL 1484), this product is not UL-listed
though it appears to be compliant in the loose sense that it alarms at
the standard set point of 25% LEL. While other products in this
product line are UL-listed, this one is not, suggesting that the
manufacturer simply doesn't care enough to pay for the appropriate
testing/listing for all of their products.

In the case of carbon monoxide (UL 2034), this product is not
UL-listed and indeed has definitely NOT been compliant with UL
standards for over a decade. The original standard (UL 2034-1992)
specified CO alarm set points at 100ppm(90min), 200ppm(35min), and
400ppm(15min) and these are indeed the alarm points listed in the
product manual (which is dated 1996). In 1998, UL updated the CO
alarm set points to 70ppm(240min), 150ppm(50min), and 400ppm(15min).
But the manual says quite clearly: "This detector has not been
investigated for carbon monoxide detection below 100ppm."

Given the note about calibration that is also contained in the product
manual ("CO sensor calibrated at 200ppm CO specific to avoid false
alarms") one gets the sense that this is a product for people who care
about buying products that won't wake them up with false alarms as
opposed to people who care about safety standards of the current
century. The similar Kidde and First Alert products are UL-listed and
people complain about more false alarms. You pays your money and you
takes your choice.

After my wife bumped a burner knob on our gas range and fell asleep while the house filled with gas, I ordered this alarm overnight. I have it plugged in near the stove. It alarms in seconds if a burner is on but not lit and has never given a false alarm.

Tested the unit on my gas stove. First trial: Turned on burner (without lighting it of course), then placed the unit on the burner facing down with an extension cord. It sounded after about 5 seconds. Second trial a day later: same steps as in first trial. Absolutely no detection after 5 minutes, even as the gas odor started filling the kitchen. I wanted to try another unit, but Amazon only allowed for a refund and a replacement is not an option. Will try another product.

Bought one of these 6 months ago. It seemed to work when I tested it. Then a few weeks ago I noticed it didn't go off when the gas on a stove 2 feet away from it was left on for over an hour. I called the company, who were kind of rude and short. They said it would only go off if he gasses were at an explosive level. It will go off if right on top of a burner or other gas source. This doesn't inspire confidence. Everyone in the whole house was virtually choking with the smell of gas and the alarm didn't go off.

We tried another one for comparison. They were both next to each other. We left the gas on for a few minutes. The newer one went off, the older one didn't.

I'll keep the newer one and maybe report back after a time. However, since these things are supposed to be a safety device I do not have much confidence in them being so inconsistent. Sure, when your house blows up they will refund the approx. $55. Think carefully before buying this.

I purchased this detector to put in my basement near a gas furnace. It replaces a much older natural gas detector and carbon monoxide detector. This particular unit plugs directly into a wall outlet, so one needs to have a wall outlet in the proper mounting location already. That was not a problem for me. So far, the unit has worked flawlessly, with no false alarms. I like the fact that it flashed a red led regularly to indicate the unit is working

There are a few comments in other reviews that the carbon monoxide detector is set too high for safety. The instructions that come with the unit say it is set for 200 ppm, and cite a US safety standard. (I tried to find the instructions online before purchase, but could not.) It appears that this trigger is beginning to approach levels where exposure over a period of time might cause problems. I find this very reasonable for my application since it reduces false alarms but sounds when there is really a problem. I might want a more sensitive carbon monoxide detector or one with a numerical readout for use near a bedroom upstairs, for example.

This unit neatly replaces two detectors and seems to provide just the kind of protection from a serious problem that I desire around the furnace in my basement.

I recently installed gas tankless water heater and gas dryer in my garage and my contractor suggest to install leak detector. This product does not has any false alarm. Keep silent.... I intentionally do leak gas slightly (everything was turn off before we do this, I would not recommend to everyone), then it detects! Keep in mind when we buy such kind of detector product, sometime it's too sensitive cause false alarm or no detection.

this product cannot truley be tested until there is a problem but i am very pleased with the functionality and features. i purchased this product because it detects natural gas and carbon monoxide and there are very few options at a good price that do both.
i live in a well kept neighborhood and had a home around the corner completely blow up due to a natural gas leak and a small child and the woman of the house did not survive. this is my second unit and i feel like it is a good investment with 2 small children and my wife at home.

This unit beats doing a paper test and then forgetting to do it. You just glance at it whenever and it tells you what level you're at. We did a disposable test before we bought our home and it was about 12ppm. I needed to do a long term test so I got the electronic test. Works great! We have 13ppm in the middle of summer with windows open in our basement. We are getting mitigation put in later this month. Then I can watch it and see if it is working.

After 10 months of use, the Safety Siren sounded an alarm at 10PM. My renter called the HVAC guy and demanded immediate service on the apparent gas leak. After hours of careful inspection, no leaks found. What was found though was a continuously running sump pump that likely would soon fail. One can speculate that there was a connection between the sump pump problem and the alarm sounding. A new detector and sump pump were installed.
