Product review (4 stars): Worked for a while - then failed - seller replaced thermometer quickly under warranty
Product failed - see comments below. Good news the is the seller was very responsive and replaced the thermometer within a few days. I am now a happy chef and I changed my star rating from 1 star to 4 stars due to the excellent warranty and quick replacement.

Bought in February 2017 and today I attempted to use and the thermometer read HH.H. Changed the batteries and the same result. Rotated the sensor and the thermometer gave various reading from -49 to 550 degrees. Thermometer has failed after light use, maybe 20-30 times. Disappointed in product quality and I can not return because "window has closed". When the thermometer worked I was very pleased - now only disappointment!!!
