Bests & Worsts Reviews from Amazon

This insta-read thermometer is great when it worked. However, just recently my thermometer has stopped working. The display shows an error message and turns off immediately. I have tried replacing the battery a few times but the issue still occurs. I noticed that Lavatools offers a lifetime warranty; however, when I contacted them about my issue a week ago they have failed to respond. I purchased this thermometer because of the great reviews and the lifetime warranty.
