I was thinking the same thing when I was buying it. I wondered how they do it so quick. I mean, they have these on the shelves within a month of Mio putting them out.I find it rather amazing just how fast Walmart adapts and evolves to whatever is selling. Oh look people are buying this Mio energy stuff lets make our own.
Also of note, the Cherry Limeade is very good, the bottle says one squeeze per 8 oz, so I did about 2 1/4 for 16.9 oz bottle. Next time I will do probably 1 1/2 for a 16oz bottle. The WalMart branded flavors seem a bit more strong than the Mio's.
