Review on Zswell Natural Detector Sensitivity Detection by Kevin Taharka

I bought this detector to be on the safe side and to make sure it was working properly. I read in other product reviews that you can test it with a gas lighter so I did as shown in the video and indeed the alarm went off after it started beeping and increasing the number of stages detected. I'll test it from time to time just to have an idea. It's a US plug (two metal), I can put it in the top of the outlet and put something else in the bottom port. The package arrived on time today, but the box was crumpled, otherwise the product still works perfectly.
