Query: Not Great

I have only had this product for about a week, although I do not like it already. The outdoor sensor is close to 20 degrees off and it is less then 10 feet from the base. The rest of the unit is okay. I just wanted a sound machine, but I bought this one because of the temp. For that reason it only deserves two stars. I cannot say how it will work in a few months or if I will keep it.
