Query: Failed in 3 weeks

Do not waste your money on this item. I bought it for the big display, it seemed to have a good reading but today its dead, it did not last 3 weeks. Also the bottom piece was loose, I had to wrap teflon tape around the unit for it to stay. Battery compartment is flimsy. The second I held the thermometer, I could tell it was not gong to last.
