Title: Consistently Off
Review: If you want to be able to buy a thermometer that is reliably wrong, this is the one for you. Every outdoor thermometer will be off in the sun, but this one is wrong, day or night, sun or shade. It is usually off by at least 10 degrees, erring on the warm side. It's not decorative enough to keep as a charming window cling either.
