Product review (5 stars): Does what it is supposed to and gives consistent results.
I bought 5 of these for different places in the house and basement and they work well - simple readouts and consistent. In side-by-side comparisons they may be a percent or so different from one another but that hardly matters from a comfort standpoint - one should be focused on big percent differences like 48% vs. 55%. Also readout agrees with that on my (expensive) dehumidifier. So works great, would buy again.
