I just received my order of 1.5ml and 3.5ml visions. Opened up the 1.5, filled with Gorilla juice, and it's working excellent so far. However, just looking at the 3.5, it almost looks too wide to fit on the prodigy since it has a juice well. Is it ok to open the wrapper even though I don't plan on using it at the moment? I want to make sure they fit!
