They cost less than half of the previous batch of seemingly identical moisture meters. Not for scientific purposes of course, but it's ok to get a good idea of what humidity is like. They are small enough to be tucked away in guitar cases to keep an eye on moisture there. That's why I bought this batch and they do what I wanted.
