Bought this at the beginning of the summer and really got a kick out of it. It was a big hit around the bonfire. Accurate and gave me a real good idea when too much is too much.
Love this device - kind of fun playing games with it while home, but more importantly, when we are out at night having a few drinks, gives me comfort in knowing where I am at from a blood alcohol content perspective.
Im always worried about getting a dwi but now that I have this I feel much safer as I absolutely wont leave the bar till 1 hour after my last drink and only if BACtrack shows me to be under the limit and if I feel that my mind and body agree with the results which so far always has. I seriously recommend that everyone who drinks no matter how often should purchase one of these for peace of mind and safety.
We keep it in the car and it's been great to give us an idea of how we're doing before we get behind the wheel. From time to time it has also been known to be a great party toy..
