Title: Great at first but doesn't hold up
Review: This product worked great at first & we felt like it was accurate. It's been a little over a year and for the last couple of months, accuracy went out the window. I usually blow on it first because I don't drink & it's been giving readings varying from 0.01 to 0.06. And if I blow on it again, it will give me a completely different result. I've tried replacing the batteries several times but it doesn't seem to help. I am very unhappy with this purchase as now I'm going to have to buy a different tester.
