Review: Works Well - Easy to Use - This is my first moisture meter, so I have nothing to compare it to, but I'm very pleased with it. I use it for checking my firewood to see if it's ready to burn. It seems very well built. You have to push with a little force to get the prongs to go into the wood and I was a bit worried that those little pins might be fragile, but they are not. They are sturdy and the case seems to be up to the task as well. I've played around with it a bit - testing a piece of wood and then leaving it in the house for a while and everytime I test it again, the moisture level has gone down just as you would think it should. I like the fact that it will shut itself off if I forget to do it. One little surprise feature is the beeping that indicates moisture level. If the level is really low, the beeping is slow. Then as you go up in moisture, it beeps faster. The cutoff for burnable firewood is 20% and if the unit measures over 20% is beeps quite fast, sort of like It's saying, "This wood is not ready!". I should also mention that the readings I get are consistent with what I see when I burn the wood. If I measure a piece at say 18%, it lights right up and burns with no steaming or hissing. If I measure one at 22%, then there will be some of the steaming and hissing after I put it on the fire. It comes with a 9v battery and I was pleased to see that it was an alkaline battery, which should last for quite a while. It seems like most things that come with batteries come with the cheapest ones possible - this was a pleasant surprise. December, 2024 I stumbled on this review that I'd done back in 2017 when I first bought the meter. (I just recommended this product to a friend and looked up my order). I can report that it is still working after about 7 years of use! I replaced the battery one time so far. I heat with wood and cut 4 or 5 cords a year - I have used this meter 100's of times since I got it and it's still going strong.

*by R***S on October 9, 2023*

I like its ease of use. I worry about the pins. They kept loosening as I use it. I have to be careful to keep them screwed down all the way.
