Review title: Useless ... Needle sticks
Product review: It worked the first time we tried it. Then the second time it was registering 100 degrees when the oven was set to 450. I set the oven to broil to see if that'd make a difference. It didn't. So I tried tapping the glass face and the needle popped up to over 500 degrees. Which the oven might have been, but I couldn't be sure. The time after that it appeared to be stuck again. I tapped it and it jumped up some degrees. I tapped it again and it jumped again. It just isn't reliable and is therefore useless.
