D MODUN Gas Detector, Natural Gas/LPG/City Coal Gas Leak Detector, 3-Pin Plug-in Gas Monitor with Sound Alarm and LED Display, Methane Propane Butane Combustible Gas Alarm for Kitchen RV Garage Hotel

Yes, very good. Detected a gas leak in the house within 20 minutes and subsequently called the National gas line and my gas was immediately turned off pending repairs. Life saver!

I purchased this alarm for my 81 year old mum who has lost her sense of smell and has a tendency to knock the gas knobs on her cooker. I was a little dubious about this alarm working from having read the reviews, however, I decided to purchase it anyway as previously, by sheer luck, a family member went to visit mum who had gone to sleep not realising she had knocked the gas knob to ‘on’! So far it has worked brilliantly, whether it takes a little while to detect the gas or not. Being elderly, mum does fall asleep but the alarm has woken her when it’s detected gas. I can truly say it’s saved her life as going by last time, the gas had been on for 4hrs and the fire service had to go in with gas masks to open all the windows and doors with mum having to sit outside for 2hrs before they let her go back in. The most important thing is this device works and if it’s a choice between not having one and having one, I’d certainly opt for the latter.

After realizing that my current battery-powered natural gas detector was broken (it even beeped outside!) I decided to try a plug-in. This product is really simple, just take out of the box and plugin. It takes a minute or two to set up but soon after the clear display was '0' telling me I was safe. Nice and reassuring. The instruction booklet states that the gas will collect around the ceiling, the detector is to be placed 30cm below and 1.5 m from the air (a window). This means it might be hard to find a suitable place if you have a really small room. For myself, I probably need to move mine further from the window but I still feel that this product has helped alleviate my worries about natural gas.

Very poor translation from Chinese to English so only guessing if it works or not

My husband thought he smelled gas, due to long covid I couldn't confirm this.After a day of his concern I bought the alarm, mainly to reassure ourselves.We used an extension lead to be able to place the alarm at the correct height. Within an hour it was beeping and reading 3.We then moved it to nearer the gas meter and it read 9 after only 45 minutes and beeped like a wild thing. We switched off the gas and called the plumber. (the alarm rapidly set itself back to 0 after the gas was turned off and the area ventilated)A test revealed a huge leak at the meter. Now waiting for the gas company to sort that out. The alarm was excellent and I highly recommend one. But do read the instructions and use it as described.Life saving!

I have had this product for 6 months and have had a false alarm. It has reset after I unplugged it. Not sure if this will be a one off glitch.

Wow

A neat, easy to use little device that could possibly save lives, it was straightforward to set up and quite unobtrusive once plugged in and doing it's job.Obviously, the test will be if there's a leak and the alarm triggers to warn us, probably something I don't really want to happen.

Très bien, service rapide pas encore eu de fuite donc pas encore vu l'efficacité de l'appareil. Facile à installer

Very good item.Delivered Nicely

Bei der riesen Auswahl,habe ich mich für diesen Melder entschieden .Die Zustellung war sehr schnell und für mich ist die Qualität genauso,wie ich mir es vorgestellt habe. Die Lautstärke bei ausgelösten Alarm ist hervorragend. Ich habe den Melder mit einem Feuerzeug getestet (ohne Flamme) .Der Melder gibt erst einige Warntöne ab und dann wird es sehr laut.

Buen producto

Très bien. Il faut le brancher sur du 220V mais ils ont tous cette obligation.
