This unit could not be easier to set up and use. After a few days I noticed the humidity going up. That made me go have a look in the crawl space and I discovered the dehumidifier had come unplugged, causing the humidity to spike on the monitor. If it were not for this very accurate unit, I would still be clueless... For that one event, this thing earned it's keep! Don't cheap out, it's worth the money and piece of mind.

We live in Pennsylvania, our Crawlspace is always around 42-44 F in the winter, I did buy this off Amazon but it was the same model. It reads 99 RH. If I put a space heater down there, as the temperature rise the RH goes down. Nothing is actually changing, just this devices ability to read accurately. I'm going to try the one from la Crosse when I get more money.
