Really like my OP3
I bought my OP3 before they went up in price and for the money it's been the best phone I have had. They, so far, have been bang on with ROM updates too. I am running the second community beta of N and it's really good. I don't really see the reason for the update to the 3T but it's nothing that worries me at all.
Highly recommended and as long as they can keep the costs reasonable I can see me getting a OP4 when they come out.
