Had a terrible musty odor in a bathroom we rarely use. Saw these online so I bought two and gave them a try. After several days the odor was gone. So problems are over. Wrong. I had failed to remove them and hang them outside in direct sunlight. So the problem in going away again. Now I have a reminder set to remind me to hang outside monthly.
Pros and Cons:
Bottom Line: Yes, I would recommend this to a friend
