Query: Unreliable

I used this item for the first time on a 5 pound pork roast. I put it in the oven at 325 degrees and within 45 mins it was telling me that it was at 160 degrees "target temperature"..............no way, no how. I checked it with a meat therometer and of course it was only 120 degrees, I hope I can return this unreliable piece of crap.
