I got my best friend a 901 for Yule; same as I have, but her's is pink. Anyway, she is still trying to learn the whole thing and I am trying to trouble shoot her over the phone. She said the pre-filled carts that came with her 901 kits are working really well, and she is getting good consistent vapor.
However, I also gave her some blank carts (same company) and a bottle of Johnson Creek juice (again, the same as I have) and that they are either dry and not hitting, or she is sucking the juice back in her mouth because they are too full.
I have been playing around with mine and realize that I am getting a little better vapor production off of the pre-filled carts too, even when they are topped off with Johnson Creek juice.
I know this is hard to diagnose without seeing the items, but could the JC juice be too thin as others here have suggested? I really like doing business with JC, but perhaps it is time to try someone else. Could it be bad cartridges?
I know all of the PV parts are good. Personally, I think she's just not refilling them correctly yet, and is still probably trying to hit them too hard, but any advice on how to help her will be greatly appreciated.
