I pre-ordered mine, and have had it since 10/26/17.
Blue shift...meh, minimal at best from my eyes.
I've run stock + root, plus a few of the custom roms without issue. I've had absolutely zero problems with mine since day 1. I get stellar battery life, and it's smooth and fast day to day. I also like the "timely" monthly updates, and the Dev and community support has been stellar! Having said all that, like Rickysidhu said, the 3 is probably coming out in 5 months, so you may want to wait. However, if you can find one on the cheap, it certainly wouldn't be a bad deal at all. And there is my 2 pennies worth ???
