"Having retired from law enforcement, I am very careful not to consume alcohol and drive. We are not heavy drinkers, but my wife and I will usually have one to two glasses of wine with dinner. Our daughter recommended the BACtrack to us so that we could get a feel for what our blood alcohol baseline would be. After seeing the accuracy of this little device, we are planning giving several for "stocking stuffers", along with some personal instruction. We feel that this is a very important product that everyone should have available." - John S.
