Actually you don't need a machine to tell you if you have bad breath, just do this:
- Lick the underside of your wrist with the farthest-back part of the tounge you can.
- Wait 5 seconds or so...
- Smell it.
This gives you a pretty good indication of what your breath smells like at close range. If its bad, go give that same back part of your tounge is really good brush with a toothbrush and paste. Yes, you may gag but it's gotta be done. Apparently 30% of the population have a 'nasal drip' which makes up the majority of reasons for bad breath. It fixed mine, according to my GF!
