I just got in an Igo-L rda from Litecigusa and when I tried to thread it onto my two devices (itaste MVP and SVD) it wouldn't thread down. I have a 510 to ego adapter and it will work using that but not on the devices alone. The only that I can tell is that the contacts on the MVP, SVD, and the Igo-L are all the same, they're flat. Whereas with the adapter it has a slit for airflow (no idea if this has anything to do with it).
Any help with this would be appreciated.
