This product is great because it lets you know when you should drive and when you should not. Some times you may feel like you are good enough to drive but then you use the breathalyzer and you are shocked that it is over the legal limit.
Given to my daughter and her husband as a gift... It's saved her and a couple of her friends from driving when they thought they were okay....again... Peace of mind!
I am in the military. I have been heavily criticized for having this unit but i don't care. Its about safety. Two of my fellow Lieutenants have been articled 15-kicked out of the army because of a DUI. If you care about your career or your job, get this unti now.
Great little gadget that lets you know for sure if it is safe to drive home, wait a little longer or stay put/call a cab. Also a lot of fun hanging out with friends having drings. Learned quite a bit about alcohol levels and BAC based on #a drinks and time. Way better to find out at home than on the side of the road with a cop overlooking.
