Hey Errol! I don't like to mess with them. I can't see to good anyways and I'm all thumbs besides. I still have new replacement innards so maybe now that I've cooled down I might dig it out of the trash and see if I can put it together again, if not I will send them to you if you want them. I'm still having good luck with my stardust cartos but they don't hold enough juice for me. I've been using 3ml cartos for too long to enjoy anything smaller but I do like being able to see how much juice I have in them.
