as tempting as OP5 is, I think better to wait for OP5T or whatever.
this camera set up isn't the best, many complaints on XDA and reddit on the quality. for that $800 or so that you're paying, might as well get a HTC U11, S8 or Huawei P10 Plus.
my point is... OP5 is excellent, many merit points. but are these points worth shelling out $800 for an EXPORT set with no warranty? I think not. the compromises they made this year were bad imo (IPxx resistance, camera... those are the "trend" this year)
seems like 1 and 3/3T were their best efforts. the even years for OnePLus not so good haha
