Product review (2 stars): not very accurate but does work somewhat.
When set at 60% on humidity mode, It will allow the room humidity to fluctuate between 43% and 52%.  The dial is not accurate and that gap is larger than I would have liked.. I would have expected a 5% wiggle room but almost 10% at the extremes is kind of a big gap.  I came back to let everyone know the ink bird Ihc200 is a 1/3 the price and works spot on with digital read outs!!
