Mostly works as advertised, except for the humidity reading on the remote sensor. Since that was not a feature that I bought this for, it's not important to me. All the same, it's something that should function properly. I do really like the projected display that shows indoor and outdoor temperatures along with time of day.
I have contacted Dr. Prepare about the remote sensor, but am getting a bit of a runaround. I use many of their products and have never had problems with customer service, so I expect that this will work out in the end.
