Update:  Wonky Results
Update:  My husband had 4 or 5 beers last night and his alcohol measured at 0.32%.  I don't trust that reading.  He was not acting drunk.  His speech was not slurred and he had none of the indications I recognize when he has had *lots* to drink.  At 0.32, he should have been acting VERY drunk and close to passing out.  I'm going to test more, but right now, I don't trust the results this thing gives.<br />Original review:<br />This is a sturdy piece of equipment and is easy to use.  I cannot vouch for its accuracy, but the results I get with it are pretty much what I expected.  This isn't a party toy or a keychain style.  It's pretty serious.  It's heavy and seems to hold a charge for quite awhile before it needs recharging with the enclosed USB cord.  There is a carrying pouch as well.<br /><br />You can get less expensive ones, and perhaps they work well, or some of them do, but I trust this one more.<br /><br />The instruction manual is not the greatest, is not always clear, but the device is not hard to figure out.
