Title: Works well enough for peace of mind
Review: The main reason I bought this gadget was to ensure that my BAC was zero the morning after a night of drinking. Although the accuracy is a little sketchy, it gives a good ballpark BAC and I trust it when it says zero, which is all the peace of mind I need. I don't recommend buying this so you can drink then drive, thinking you are under the legal limit. It's not accurate enough for that, not to mention that would just be a stupid plan!
