Bought this a while back. Opened today.
The box seems poor done.
You might have to be careful. As u can hear the sound its probably made of glass.
Red is charging mode
Green is fully charged
So it was leaking from the bottom and i left a feedback on aliexpress. And I found out another thing
Its actually separate able. Because it is seperateable you have to screw it well if not water leakshttp://www.arevainna.com/wp-content/uploads/2019/01/img_6211.mov
Press the button to start. It will actually automatically stop but well i didn’t want to video so long.
Overall item seems to work fine even though the packaging is like crap.
Poured cold water in and also in cold air con room. The hydrogen water bottle seems to not work well. Very little bubbles but if u take out in normal room temperature it seems to work alright.

“Also the white ball prevents the electrode sheet from oxidizing by continuously rolling, but it seems that the effect is not very good.”
