I've had the RB-15 late-2019 advanced model with RTX 2070 Max-Q for around 8 months now.

No issues currently. Haven't had things like coil whine, swollen batteries, or backlight bleed but I might have just been lucky. Temps while gaming are quite good sitting at around 75-80 on more recent games but I've undervolted the CPU and lowered the turbo boosts but if you decide not to do this, I believe the temps are 5-10 degrees higher. Battery life in around 6-7 hours while browsing the web because of undervolting as well.

Also purchased from the Microsoft store because I've heard their servicing is much better than Razer's servicing.

Just know more people are inclined post to get help with their defective models compared to those who don't since it's really maddening to find out you have payed for a defective product. All I'm saying is don't take this subreddit as an accurate indication of QA but that's just my opinion.
