Product review (2 stars): Worked great for the first 3 months then the temperature reading ...
Worked great for the first 3 months then the temperature reading started acting strange.  It would say the temperature in my office was over 100 degree F or the screen would go blank all together.  I would replace the battery and it worked fine for about a week and then the same thing would happen again.  I finally gave up after 5 months of use.  I do not recommend this product.
