This is a piece a junk, I should have read the reviews first. Since you can't even return this item save your money and forget ordering this thing. I contacted Amazon and asked them to remove this from there list since it doesn't function correctly.

This thermometer is so inaccurate it is not even funny, after receiving and using the first time, I calibrated it using cold ice water and boiling water. The temperatures were way off. I went to return it only to find out that it can not be returned or refunded. Do not make the mistake I made by buying it.
