Product review (4 stars): Decent monitor at a good price.
We had some surface mold growing in the house this winter, and the mycologist recommended that we get some monitors and place them in several spots in the basement, and in our bedroom, where the mold was forming. It is nice that you can find out what the levels are on other monitors from the main one. Seems to be reasonably accurate. Interesting to see how different the humidity levels are at different heights in the room. We will use the data to determine if we need a more heavy duty dehumidifier for the basement.
