Drew: I just received my replacement cartos for the defective one that came with my Igo. Well, now I am a happy person because the carto I had left was also defective, and these new ones (you sent me 3 so I thank you) are not the same. The two that came with my Igo kit had a problem--
juice either ran on through or just sat on top of the filler. I could not take more than 5-10 draws before the taste changed to that "low on
juice" taste. I was so disappointed. But I have filled one of the new ones, and the
juice soaked right in like a carto is supposed to. This pv is awesome when it is working right. I just hope the other 2 cartos are good also. Thanks so much for great customer service, and if someone complains about their Igo carto, they probably have a legit. problem. Appreciate your time.
