When I received the bottle, I noticed that the membrane was closed with a special cork, but it dried out anyway. I started doing tests with the H2Blue test. The bottle showed a hydrogen production rate of 0.7 ppm. I contacted the seller (Steve) and he sent me a video on how to improve hydrogen production. Tried several times, nothing helped. So I sent this bottle back. Then I ordered a second bottle. This time the membrane was wet. I did a test and the new cylinder showed an excellent result (1.2ppm). I am very grateful to Steve for his advice and high quality hydrogen generator. I'm going to buy some more balloons for my parents.
