Will show if you have had too much to drink
This thing is pretty awesome. We have all had times after we have had a few to drink and  we are not sure if we can drive. This will help you determine if you have had too much.  So I can’t post the picks but I tried this sober and it gave me the reading 0.0. And then after a few drinks came up as 0.04%. Comes with 5 blow straws. It gives you a countdown and then you blow into it for 10 seconds
