For the price, this item works great. It is not a detector that sniffs the air for readings like the long probes you see energy companies have. It is a smaller device that works well for testing for natural gas leaks at the source. This means you must hold it gently against an area that you want to check for a moment. It is great for checking around valves or other seals that could leak gas such as your water heater tubes or gas stove. I had a 1lb propane tank shut off and it was able to detect residual propane on the tip of it, which is what Xcel energy did one time with their probes in front of me, so if it can catch that, it likely will catch other non-smelling leaks, but you must go slow around the areas you are testing and also turn the S on for sensitive.

This device does require a 30 second zero level calibration each time you turn it on. I used it to detect and pinpoint a natural gas leak around the gas valve controller on my water heater. Very easy to use and was very effective. The display and audible alarm quickly reveal how much gas is being detected. I thought the price was good too.

I purchased this detector in December. I ran it through some tests and the sensitivity and detection worked great. Of course I’m also keeping in mind this is 20ish dollars device. I’m expecting it to work and you should too but I swear some of these reviews are expecting a professional level tool for a pocket tool price. Stop that;) I used the detector and it performed very well the 1/2 dozen or so times I used it between Dec-April. Unfortunately when I went to use it the last time it wouldn’t turn on. I swapped a couple different pairs of batteries and it was still dead. I was disappointed of course because although it’s not expensive I was hoping to get some years not months out of it. I reached out to the company through the Amazon App. They replied in less than a day. They asked some expected questions and I gave them the information along with a few pictures of the device which still looked brand new. After that message with the pictures they informed me one was on the way and I’d have it in a few days. I actually received it the next day. Of course the ideal situation is the product never fails but if it does it’s nice to get no hassle replacement. From my first message to having a device in hand was about 5 days. For an inexpensive product I’m impressed with how attentive the CS was. I’ve used the new one a couple times and it’s working well. Do NOT buy this product and then be upset when it doesn’t perform like a Sensit product. DO BUY this product if you’re looking for an inexpensive Homeowner grade detector with an easy to process warranty the company stands behind.

Great to have as its portable and I can take with me if need be. We had a strange smell so I bought this for peace of mind. Definately, worth it! Comes with a soft case and batteries. Very easy to use.
