So Ive had my XHaler for a few weeks and LOVE it. I have used all the attys but mostly use 808 cart on the fly. I jut screwed a Greencig cart onto the 808 adapter that I got from Drew and no go.....I can hear oit engage but I get zilch....tried loosening it......still no go........then I put Greencig right onto brass 901 endcap and still no go. Does anyone know if you can get a Greencig cart to work with an XHaler? Drew?
