You never know how bad your breath stinks even though you brushed your teeth. One manual way to check it is by putting your hand onto your lick and smell it, and that will be the smell of your breath. However it is unhygienic and disgusting to do that, and your hand will smell.
Japanese are one of the most creative human beings in this world that invented this Breath Checker Mini. The tester will tell you if your breath stinks. The bad breath etiquette tester detects acid-volatile sulfide and hydrogen carbonate gas to determine how bad your breath is. To test your breath, you need to take off the cap, shake it four to five times, blow into the front and wait for five seconds to get a rating from 0 to 6. There are three different colours available for the portable device, which are pink, blue or green. It is powered with AAA battery.
