Does anyone have experience with the FoodMarble Aire 2? It tests fermentation levels of hydrogen and methane (only). Most of the reviewers suffer from SIBO. I haven't tested for SIBO yet, but I am lactose intolerant, yet still get large amounts of gas even when I stay away from lactose, which is always. I think this product might help but I'd rather hear some real life stories before shelling out $250.
