Need assistance

I recently bought the 32oz bottle and some sips (peach tea, raspberry tea, fruit punch) and I can only get the sip to last about 3/4 of a bottle. I tried on settings 2 through 5. 2 and 3 had no noticeable flavor and 4 was weak but 5 had a decent enough flavor I could live with. I bought everything from Walmart don't know if that means anything. I don't know if they would be better if I got from the cirkul website.
