I got this laptop while it was on sale. I hesitated for a while at first as I had seen many negative reviews regarding gigabyte laptops but after having used this laptop for a while now, I can safely say it might just be the best laptop I've had in a while.Build quality: The build quality on this laptop is fantastic, all aluminum so it feels really premium. It also has a really nice design in my opinion. Really muted which I happen to like. My only concern is the hinge. The hinge just doesn't seem tight enough? It causes the display to shake sometimes but never when i'm typing so that's good. It's also a one hand open. Laptop is pretty light as well but the power brick, being 230watts is pretty big.Display: Wow, the display is really great here. The 4K OLED panel is really bright and really vibrant. It doesn't get past 500nits but it was a sacrifice gigabyte had to make to get good deltaE values. Contrast is amazing, color gamut is really good on here. Only down side is that it's 60hz. Hope to see high refresh oled screens on laptops sometime soon. I can see banding sometimes but I rarely notice it.Performance: The 1660ti along with the i7-9750h is a pretty good spot for me. Getting gaming out of the way, I usually get around 120fps in Apex Legends, 100FPS in Resident Evil 2, 150fps in Overwatch &  90FPS in Soul Calibur. All games were in high settings, with the exception of overwatch being at epic settings and all games were ran at 1080p. I can't push many games at 4k. In terms of Video Editing and Rendering in Unity & Blender, the 1660ti also has studio drivers on the AERO and render times have been pretty good as well as editing video has been pretty smooth, though I don't do video editing often.Thermals: Thermals on my unit weren't great... but they weren't all that bad. I've never experienced any thermal throttling. GPU temps are usually around 75c-84c under load and CPU temps are higher at around 90-92c. You can drop the temps by about 3-5c by enabling max fans, but they do get REALLY loud at that point.Keyboard & Trackpad: I love the keyboard on the AERO. The backlighting is plenty customizable and bright. The keys have a pretty nice travel distance so it feels pretty good to type on. The trackpad is glass so it's really smooth, and it has windows precision drivers so gestures and such work like a breeze. It also has a fingerprint scanner, which is quite fast and works fine for me.Software: The laptop comes with no bloatware except for GIGABYTE Fusion & the AI software, which I guess aren't bloatware because they're pretty useful for controlling fans, keyboard lighting, etc.. Almost all my drivers were out of date but hey, control center makes it super easy to update drivers and in about 30m, all my drivers were updated. I personally like and have no problems with control center but the AI software still seems gimmicky.Fan noise: Fans do get super loud under load but otherwise, I hardly hear them. As states above, max fans do sound like a jet engine. You also have full customization over the fans using gigabyte fusion.Battery Life: Battery life for me while typing docs, browsing the web, 40% brightness and keyboard backlight on was about 4-5 hours for me. Haven't tested it while gaming though.Camera: The camera is the worst part about this laptop for me. Bad quality, bad position. Rarely use it though so I don't care much. They have a privacy cover for it though so for people concerned about privacy, no tape required.I'll continue to update this review as the months go along using the AERO, but so far, really happy customer.Some other things:-Laptop has a second m2 slot for SATA&NVME SSDs, gigabyte also includes extra thermal pads for any secondary ssd you might add. The Stock SSD is really fast too.As of November 17, 2020, I populated my second m2 slot with a Sabrent Rocket 1tb nvme SSD, and have no issues with it on the laptop. Speeds are really fast too at around 2000mb/s r/3000mb/s w.-I've seen alot of complaints with the wifi card on the AERO, but wifi experience on my model has been excellent. No problems w/ download & upload speeds over WiFi on my model and no drop outs.***Update***It's been one month w/ the Aero 15 now, no issues so far. Still love this laptop.**11/17/2020 Update*My GPU fan started making a loud grinding noise after about 3 months of owning the laptop. I'm not sure what caused this, but my guess is that the bearing went out. A couple months following this, the fan completely gave out and stopped spinning completely. I decided to get a replacement fan myself on AliExpress and replace the fan. Replacing the fan was pretty easy and while I was at it, I also re-pasted my CPU and GPU with Artic MX-4 thermal paste. Following the replacement and re-paste, my fans are much quieter now and thermals are much better than they were before. I'm able to maintain 3.8ghz on all cores during full CPU load. I'm still dropping my rating by 2 stars as I am disappointed that the fan gave out in such a short time. Looking at reddit for the experience that other people had with this laptop, it seems to be a pretty big issue with this model. I'm not sure if this holds true for the 2020 model, but I can only hope it's fixed. Other than this, I have had no more issues with this laptop and everything has still been fine, especially performance now following the re-paste. The fan model for anyone curious is: PLB0701S12HH. My opinion still stands, I still think this is a great laptop, but I hope gigabyte does fix the issue with the fans. If you look on reddit, people have guides on how to fix the fans without buying a replacement.
