Ketone Breath Meter

Preowned from a smoke-free home, this was given to me by a friend. It does have brand new mouthpieces in a package. I do not know anything about using this product because I never did so buyer purchases it as you see it. I will be happy to answer any questions if you have some specifically. I just put new batteries in to make sure that it turns on and appears to be working. Please reach out if you have any questions that I can try to answer for you before purchasing. I hear it is good for low carb diet. so you can check your ketone level. Fast shipping!
