Great handy tool to have.
I had a pipe freeze and leak this winter and needed to figure out what had been soaked. This worked great. I set up my fans for a while and used the meter to monitor when the moisture level had gone down to an acceptable level for me to complete the repairs.Now that I have it on hand, I am finding more uses - checking my firewood and other fun things.

decent enough
It's pretty nice but I'm knocking a star off for not having a wood density setting, you really need that if you're measuring anything other than whitewood. For the price there are cheaper options on Amazon that work just as well. If I was just shopping in a store and this was my only option, it would work, but I'd need to calculate the lower values for other kinds of wood, making it less handy.

Great way to ensure your firewood is ready for the Woodstove. Easy to read.

Must have in every household
It’s worth every penny. We ordered this item because we are buying a house and sure enough a day after we ordered it the house flooded. This made a big difference for us to know what where and how much the damage would coast. I do recommend to everyone to buy and keep it handy

The percentage ranges are wrong for dry climates like the desert southwest.
If you live in Las Vegas, Southern Nevada or Arizona, heads up that this product will work but the ranges are wrong. Drywall in the desert southwest is typically 0%, which displays as "--" and you can't tell if it's actually working or not. Anything above 5% is concerning. 15% is still considered "low" by this meter, but that actually indicates serious water problems.
