While browsing around today (not even sure where now!), I saw the youtube video that Benjamin put up showing how to refill carts with the "condom." I just tried it and it is the best thing since sliced bread. I have about 5 bottles of juice that I have not been using (and therefore spending way to much money on new carts), because it was always such a messy pain in neck. Thank you so much! Brilliant! Just absolutely freaking BRILLIANT!!!
I just recently saw that too! And yes, it is soooooo much easier!! It's actually one of the reasons I went ahead and got some of the turbo carts!!
One strange thing though. I was filling a few last night (brand new blanks) and one of them immediately had liquid coming out of the battery side. I couldn't get it to fill properly so I set it to the side to mess with later.
Overall though, so far I love these carto's!! I forgot how nice it is to be able to switch flavors so easily and not have to refill or drip constantly!!
