This is such a piece of junk I'd be surprised if it told the right temperature. It wouldn't stick to a window, the screw the suction cup is attached to is too short and keeps falling out AND, it's warranted through to company and asks the consumer for more $ than I bought it for to take advantage of the warranty. Sierra should think twice about selling this item. I want to ask STP for a refund but it's not worth $2 of my time.
