Amazon has excellent return policy
on January 7, 2016
This unit is absolutely unreliable. I owned many humidity monitors in the past. This unit's readings are way off.
I placed it in 1 room with 2 different model humidifiers while the other models showed 34 and 36 RH and stayed there, this unit showed 11 RH even after more than an hour.
I checked it in a different room with a different model of humidifier right next to it, that I tested before and readings were again up to 30 RH less.
I don't know if this unit was defective, but after reading other people's reviews I think it's a common problem.
Amazon has excellent return policy, you can give it a shot if you want, but I would suggest to try other models.
