Query: Junk!!! Waste of money!!!

I ordered this in Febuary, an did not need it until now. Well, I should have tried this out when I received it. Like most of the others, the reading was fast, but it was wrong, every time.. My grandson had a temp, and it said 93 degrees. All I can say is this is not worth a penny!
