I had one of those as well, but didn’t have any faith in it and picked up a digital meter. I found the lopi one annoying to use/read.On a side note to owning a lopi. They give you a free basic moisture meter. I think it reads lower than what the woods actually is (yes I check at 70* on a freshly split face). I like to place the wood against my cheek and see if it feels warm. If it’s wet it will feel cold. If it’s dry it will feel warm. If it’s in between it will feel in between . I still use the lopi one as I’m cheap and don’t want to buy another one but I don’t put too much faith in it.
