Set up took about 2 hours or so. Took about 2.5 weeks for the system to stop producing bubbles in the water. Works great and tastes good.

MERCHANT COMMENT: Thank you for your review! Just to note, oxygen bubbles in the water are not a defect of function, but from varying oxygen levels in the source water that the system breaks down into tiny bubbles, so they may come and go throughout usage, however, dissolved oxygen is natural, harmless and makes the water even more revitalized.
