Very helpful manual to have--great go to for quick do-it-yourself repairs and answers questions. Helpful pictures and instructions.

EVERYONE needs one!! I use this item WAY more than I thought I would when I purchased it. I bought it because I was buying a humidifier and I was curious as to how much humidity it was really putting in the air. I didn't think this thing would save me money!! I had a leak in my basement. I wasn't aware of how bad it was. But what I did notice was the humidity levels were rising down there. I live in Colorado it's extremely dry. I quickly knew something was up once I saw those levels rising. I monitored my basement with this unit for quite sometime. Once the levels evened back off I knew everything had dried out from the leak. Like I said, I never thought this item would save me so much. This may seem like a silly review. But trust me, after the experience that I had I would HIGHLY suggest every one of my friends and family members have a Humidity Monitor in their house. Quite possibly two!
