My wife bought me this to replce the original Thermo Fork I had for about five years that I got from Walgreens for $9.95. The 1st time on the grill this thermometer went haywire and flashed several different readings. I changed the batteries thinking they were low...same result. Sent it back thinking it was defective and was chastised by the cust service rep, inferring i was doing something wrong. I got the replacement a couple weeks later and had the same problem. Needless to say it went straight into the trash along with my money!
