Product review (5 stars): Responsive and easy to use.
Within 10 seconds, I'm getting an accurate and precise reading of temperature, relative humidity, and web bulb temp.

The tip makes it easy to access wall voids and ductwork.  The hold button allows you to hold that reading until you can bring it to where you can read it.  The included carrying case and instruction booklet are well made and easy to understand.

Nice design, good implementation.

Recommended.. Solid instrument so far.
