No Hydrogen present – Item took a month longer to come, arrived and it didnt work. We sent videos of the weird noises it was making when charging and they would suggest us to read the instructions again. In the end they sent a new base over with a very condescending email, which is fine in all, though we have just tested the bottle for hydrogen with a Hydrogen test kit. Water should turn clear with the solution and it stays deep blue indicating that there is no hydrogen present. Will be contacting consumer affairs with all my findings. Very disappointed for $120 drink bottle that doesn't do what it says. 1st photos will include 1 drop and 2nd photo will have 10 drops
