It is hard to gauge how much oxygen I am getting per time and how much if any is left in the canister. It seems to help some but I am not sure how much. I do not have an answer for how to gauge it but perhaps you can figure a way to better measure usage and amount left.

Out of 2 of the last three dozens I have bought there was 1 can in each dozen that had no oxygen in them. When I called 2 months ago they said they would send me a replacement can . They never did. You owe me 2 cans o oxygen.
