hey new to the forum. I just bought and I am using an eroll. great device for first timers working on getting a good juice. if anyone has one I do have a question. (cant post in the eroll forums yet) I am wondering how you know if a cart is bad. It has what looks like condensation on outer parts of the tank. it was slightly leaking also. I might of broke the tank by removing the top (that's how they say to fill it). I sinced an using a syring type to add fluid. wondering if I broke the tank some how or if it just went bad that quick?
