“Very Accurate and pretty fun! You can start off being 0.0 and then while at home, have a shot of whatever or one beer, then test to see who much it takes to show a positive reading. You'll be surprised that you don't have to drink much before you are at the LEGAL LIMIT. Then you can find out how long it takes for your level to go down. Very interesting for sure. I only bought 2, I need to see if they are on sale again. Pretty handy to have.”
“I bought this Keychain for my wife to use when she goes on her girls weekend. Her plan is to see how everyone is doing while they're out partying. It's really easy to use and seems to be fairly accurate.”
“My device did not work upon delivery. I am returning it. Customer service was great and I was told you need to buy the more expensive ones for accuracy. Very disappointed.”
