Very satisfied.  Readings corresponded well against local forecasts when I tested outdoors.  Now feel confident about what my house relative humidity is.

A few criticisms:  Some display fonts too small,  response times a bit slow for large changes (e.g. going into colder room), changing modes requires holding down the mode button longer than expected.
