“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.”
“Broke within a week of using and does not give accurate readings, id like to try another one of the more expensive options to give a better review if it’s any better quality but I will not be purchasing it again after this one…”
“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.”
