Negative Positive
Title: Worthless
Review: I bought this for use in a small safe to keep the contents, mostly papers, dry. I placed the unit into the safe along with a hygrometer. I checked the hygrometer after an hour or so, and it showed about 65% humidity. I left the safe closed for several weeks. When I opened it again, the humidity was still about 65% and the papers were still damp. I did not do anything to reduce the humidity in the safe.
Is the review positive or negative?
