This only lasted a few weeks and now reads 0.0 overtime. Yes, I put new batteries in it. When it worked, it was awesome. But this item does not last.

gifted two of these babies to my friends for their birthday and they both broke within two weeks of purchasing them.

This tester was so inaccurate that it could not be dependably used to test alcohol levels. When it counted, I couldn't get meaningful readings. Perhaps mine was just broken?

I bought this 3 months ago, and I am very happy I did. It makes me aware of what I am drinking and how much prior to driving. Outstanding product and easy to use and is very accurate. I will keep it calibrated to ensure it's accuracy

I use this for multiple reasons, but find it to read false positive easily. Testing after brushing my teeth and eating certain foods or teas. Is this common? Also I have had readings from .04 to .0 then back up to .03. Please advise. Also how durable are they and what would make them un calibrate?
