Product review (5 stars): In my opinion this is a very good product for the money
In my opinion this is a very good product for the money. I placed it out my backdoor attached to a steel bell of all things. Through rain, snow and direct sunshine temperatures 31 to 54 F humidity 62 to 86 (winter months mind you). I've only checked it against the local weather station with only a degree difference. Works great and like I started with Very Good Product.
