So, I just pulled the trigger on a OnePlus Two. I've been with my Nexus 5 for just over two years, it's served me well, but the itch got to me and by chance I got an invite on their forum, so thought, what the hell...
Anyone here have experience with OnePlus devices? Things to look out for, etc? I'll certainly report back once I have it in my hands...hopefully it isn't a long wait. And for anyone who wants invites, I should have some in the near future 
I got a Oneplus X invite yesterday morning but decided not to buy it after reading mixed reviews. 
I know that doesn't answer your question about the Oneplus 2, but I thought I'd share my experience anyway...
