Query: Disappointed

Very disappointed in this unit purchased from Amazon, used once on my smoker for ribs, next in the oven for a prime rib roast. Oven temp set for 225 F. but the meat probe kept going off the scale with an HHH reading. Looks like the coating over the steel wire going into the probe burned off. Don't waste your money on this unit as it will not hold up.
