Thanks for all the responses. I've stopped using it and have gone back to my eGo-v, at least for now. I tend to get OCD about things and my frustration with this and having to make adjustments for it is frustrating me. It's not a collar issue with my PT2 as I haven't even used it with the collar on the MVP. My greater concern is with my collection of T3Ss. They may not be genuine Kanger devices but they are what I have and to start replacing other stuff to or making modifications will just make me start to give up on vaping. It should not be this frustrating. Shame on innokin for not following the standards is my feeling. Again I'm just feeling frustrated but at this point I am thinking of just taking a loss and try to sell it to someone at one of the local shops. I'm very disappointed. Thanks for listening to my rant I just hope it helps someone else in the same position as me.
