I haven't tried the vornado yet but I just got 2 ce4's and they are very disapponting!! They come with some type of moisture or primer liquid and taste horrible. I've rinsed them and hope this helps. I'm searching for help right now on fix so thought i'd share my experience in the meantime. I am loosing faith in star dust, visions, stones and my son just got a dct
tank and its working fine. I guess i'm going to stick with cartos. All I want is something to work without filler and hold a good bit of
juice!!! Any help out there. Thanks. p.s. don't mean to pick on anyone supplier wise as I like most of them, they are just trying to make our healthy hobby better. Just saying!!
