Product review (5 stars): I could have spent a lot more...
So glad I didn't.... I got this to take reading around my house to assist me in diagnosing a humidity problem I was having last summer. (my house was built last January)So I could do battle with the builder's AC company. I work for a contractor and at work we have the $500 variety... This one operated side by side had the same reading within 2 tenths of a percent of humidity!!!
