Product review (2 stars): You had one job.
I never given a 1-2 star review for any product Ive ever purchased but this had one job and one job only: to tell me the temp in my bedroom. After it saying it was 61 degrees, I brought it into the room where my actual thermostat is. Its off by 4-5 whole degrees. Literally does not work for the single purpose Ive purchased it for and its not returnable.
