“These are a necessity paired with the keychain breathalyzer. I changed them out to make sure I get the same results! I promise you anytime you use this around others drinking EVERYONE wants to try it. That’s why these are a MUST have because I’m not putting my mouth where someone else’s had been! Simply take the mouthpiece off and put on a fresh one! You can always wash them to reuse!”
