4.8 / 5
Little Device!
I have an IID in my car and this thing is apparently very accurate. Little device can help make responsible decisions or just be fun with testing in your friends.
Peter R.
Great Accountability Tool!
This has given me extra peace of mind to know that I or friends won't try the ‘I think I'm just fine to drive home tactic. This device is small and can easily be added to a key ring or put into a pocket.
Laura K.

Jessica M.
Compact & Convenient!
This unit is small and effective. I keep it in my purse, but is small enough … Most importantly, it's accurate. A decent gauge to help a person make smart decisions.
