Query: Don't Buy This Product

I am a cheesemaker and need precise temperature readings. I bought this product to replace my Polder, which kept needing new prongs. I know that all digital thermometers have issues: prongs wear out or main units fail after x number of uses. But this product takes the cake! It did not work at all from day one: gave ridiculous readings (e.g., lukewarm water read 180). I returned it to Amazon (gotta love their return policy!) and ordered another unit, assuming the first one was a fluke. Wrong. The second one also failed to work properly from day one. I give up on Taylor.
