This indoor/outdoor thermometer worked great.. until it didn't at about the 10 month mark after buying it. After that, the outdoor sensor unit just stopped working.  I changed the batteries and hoping this would fix the issue but it didn't.  With this product, you get what you pay for, which in this case if a decent thermometer for most of a year before you find yourself looking to replace it.
