It’s a game-changing invention for those who want to know if they should be driving after consuming alcohol. With the information, you can see when you’ll be sober again and it’s portable. There’s no mouthpiece so it can be shared between people so everyone can be safe. This company has made $2 million and they’re coming out with improvements to their invention. The new ones won’t need to be plugged into a phone and will be more accurate.
