Bad product
The item was received in bad condition. It’s clear that the wrapping had been opened before it was sent to me. It appears as though someone used it and then rewrapped it—poorly.

I bought this gauge mostly to check if firewood is dry enough to use in our wood heater. It works great for that purpose, but it seems the manufacturer designed it to show if construction materials are dry enough to use without risk of mold occurring. I expect it would work well for that as it is easy to use and easy to read the display. An added bonus in this price range is the calibration contacts in the cap. You can check it before you use it, to make sure it is reading accurately.

The biggest benefit is the peace of mind for checking firewood. Before getting this meter, I was just guessing if my wood was seasoned enough by the weight or the sound it made when knocked together. Now, I know for a fact that I am burning dry, efficient wood. This means less smoke, cleaner burns, and not having to worry about excessive creosote buildup in my chimney. What I appreciate most is the absolute ease of use. The screen is clear and easy to read, and the interface is incredibly straightforward.
