Product review (1 stars): Buy a cheap fan instead.
My apartment gets way hotter than outside, but "way" wasn't specific enough. I was shocked to see the temperature almost always 11 degrees F higher, sometimes even 15. Tonight I left it outside to test it. It said outside was 9 degrees hotter than what it actually was. Completely unreliable, can't even tell myself to subtract X degrees. Should have put money towards a fan instead.
