Title: Cheap and Shoddy
Review: The battery compartment isn't manufactured to hold the battery in contact with the leads properly so the units flake out a lot. You can fix this yourself by putting in a piece of paper or something to push the battery against the contacts, but even when you do this you may have a hygrometer that doesn't work so well. I find that the calibration knob doesn't really function well. With quality this low, what's the point?
