I purchased this laptop this past November and have had only one issue with it, which was actually an issue that I myself created. I couldn't get the webcam to work! Turns out it's managed through the SmartManager app and had been toggled off. Gigabyte was great in working with me to figure out the issue; fast response time, and best of all professional and kindly correspondence. I felt a bit silly that I had just been overlooking the solution, but was relieved I didn't have to return a $2,000 laptop for such a small issue.As for the laptop itself... it's amazing! I've played some recent AAA games like Shadow of War on it on ALMOST the highest settings and had no issues. I run most of my games through the NVIDIA GeForce Experience and it really helps in finding the best graphics settings for the most optimal performance. I find that when you try to output to a 4K monitor the smoothness drops down quite a bit when you try to play at 4K settings, but when you play from the laptop itself it's able to chew through high settings with ease.The only thing that I wish was different is the fans. Once they get going they're loud, like any other gaming laptop, but it's actually the quieter setting that bothers me. When my laptop first boots up it's on the "Quiet" setting and emits a loud whining noise. If you go into Smart Manager, select the "Quiet" setting again though this seems to fix the issue and it runs almost silently.If you're big on tactile response of the keyboard and track pad, I think you'll find the keyboard adequate but the track-pad lacking. The track pad is very squishy, and doesn't give much back in terms of whether you've clicked or not. Thankfully you can also just tap to click so when I'm not using an external mouse this is usually how I use the track pad.Flex is minimal on the keyboard area, which helps in making it feel sturdy. Monitor flexes slightly when pushed from the left or right, but is somewhat negligible. Nonetheless I usually choose to lift from the center when opening the lid. Monitor resolution is fantastic even if I do wish that the refresh rate was higher. Monitor can be set to either 30 or 60Hz. Depending on whether you want a 4k resolution on a 15.6" format you may be better off choosing a 1080p version with a higher refresh rate for a smoother overall performance. That being said, I have yet to have issues with this laptop in regards to smoothness of playback on anything from YouTube videos to lengthy gaming sessions.One final thing to consider: the power block is seriously beefy. It is genuinely enormous and is quite a bit bigger than any oother power block I've seen on a laptop. The laptop itself is not dainty, but consider that with it being a gaming laptop it's not exactly the most power-efficient computer and that you will more than certainly need the power block with you when you take it anywhere. In my experience the battery can last anywhere from ~2.5 hours when using it only for video playback and document processing to as little as 45 minutes when gaming.Overall, I would say that if you have around $2k to spend to spend on a laptop this is an excellent investment. (At the time of writing this the model that I bought is actually $100 cheaper than when I purchased it - $1.9k vs $2k.) It's priced competitively in terms of specs, form factor, and performance, so I highly recommend this one! I do have a few things that I stated above that knock it down from a 5 to a 4 star rating for me, but don't mistake that for my being dissatisfied with it! Worth every penny.
