It is fantastic. I returned it because I got buyers remorse, but I wish I never did because I got it on a black Friday sale. It ran all my games, smoothly. I played black ops 6. Rocket league and hell divers 2. No I'm here just playing on the switch 2 lol

Got it cheaper than Newegg, does everything I want it to do. Kinda wish the keyboard was individually RBG instead of zone RBG. But it’s great otherwise. Minor negatives, can get a little warm, use a cooling pad if gaming. Battery life is okay when NOT gaming. HD video or gaming will kill the battery in an hour. Battery will drain faster than it charges when gaming. Take occasional little breaks if you plan on marathon gaming.

I felt like I did plenty of research going into this computer purchase, compared benchmarks and hardware to ensure I was making a choice in product that would last 3-5 years. Let me tell you, this laptop isn’t it for my application. I needed a laptop to be mobile and edit content, primarily graphic design and 1-5 minute video editing. This includes using the entire Adobe suite with either one or multiple programs (not all at once). I found my experience with this laptop to be subpar at best. Right away I was leery of the AMD processor, I much prefer Intel. I cannot prove that this CPU was the root cause of all my issues, but I have a feeling it was a contributor. I was very disappointed with the lack of reliability, and it seemed every time I needed to use the laptop, there was some issue. And then of course if I gave it a little time it would finally come around, just enough for me to question if I could “make it work” in the long run. It got to the point where I started documenting the issues 2 days in and noted weird things I was finding since this laptop just didn’t feel right. Below were several of the things I noticed in just over a week of owning and using daily. Keep in mind I came from a M3 Pro MacBook Pro prior to this. Delivered: 9/20/24 Issues with laptop: Google chrome opens first search with bold text every time, super annoying. Incognito mode does same thing so doesn’t seem to be an account setting/issue Initially opened using Yahoo as search engine with brand new Google Chrome download. Could have been an issue with previous extensions that I had, since I had logged into google first before searching anything 9/23 Laptop was at 10% and went into power saver, keyboard dimmed and brightness went down. Plugged it in for an hour, go to turn it on, black screen. Plugged into other outlet (neither outlet is switched) and it finally fired up 10 minutes later. 9/25 Got home and opened laptop, won’t connect to home WiFi, which it’s been connected to for almost a week and has remembered. Turned WiFi off and on again, and now says No Wi-Fi Networks found. Need external WiFi adapter to use internet now. 9/26 Plugged in hard drive (offline) to work on project, computer won’t read hard drive. Previously Norton wanted to run a scan every time I plugged in, so not sure if that’s why it’s not recognizing the drive but I wasn’t able to do work off the SSD until I had WiFi again 9/26 Was editing a project with computer, closed lid for 15 minutes, came back and screen is black. Won’t turn on or restart… 20 minutes later it turns on after deciding it wanted to be shut down, and tabs are now all closed and unsaved work lost… not cool. 9/28 Finally used Adobe Premiere Pro for the first time on this device, playback is CHOPPY, it will play forward when previewing, then chop back a few frames, then play forward, they chop back a few frames. Not a clean simple playback to review my timeline and see how my project looks… Trackpad pinch to zoom doesn’t zoom-in on timeline in Premiere… throws off typical workflow, VERY annoying 9/29 Perfectly on que… blue screen of death “Recovery” while turning on… time to get a MacBook. Another odd thing: EVERY time the computer restarts MSI Center and Xbox re-pin themselves to the taskbar I also added quite a few add-ons to “try” making the laptop feel more like a Mac. I added things like 3 finger drag, spacebar preview, phone link, changed photoshop and Illustrator settings to allow pinch to zoom… and even with all of this to help my workflow feel more like a Mac, the clunky computer workflow and unreliability kept me feeling disconnected from my work.

I am doing this review on my new laptop! This thing works great, it starts right up faster than any other laptop I've ever had. It runs all my games on full and doesn't crash. I had another msi laptop before that lasted seven years before it started to slow down a bit, and decided that I would get another msi. This thing is great it is not loud and is very easy to set up. I play a lot of video games and this is awesome.

Great mid-range gaming laptop. Keyboard feels odd compared to my zephyrus g16. Speakers are ok as well as the display. I did swap the main nvme SSD with a 2tb Samsung 990 evo plus and it’s been phenomenal. Battery life is ok but definitely do not use it too long away from the charger. The one thing I definitely like about this laptop is the cpu. Also it’s really easy to open and work on, which is a huge plus for those of you who want more storage or ram. Overall, it’s a gaming laptop that gets the job done but definitely consider swapping the nvme.

I wanted a new gaming laptop because I was using mine for work efforts. The one I had didn't have a 10-key number pad, and as a freelance bookkeeper it was driving me nuts not having one. I scoured for a laptop with a number pad, and found this one. While I appreciate that it has the number pad, it feels like it was added as an afterthought. The number pad itself is squished and has an awkward layout. Each of the buttons is smaller than the other buttons on the keyboard. On the flip side, people normally find a gaming laptop for its gaming capabilities. I have nothing to complain about here. I haven't had any issues playing the games I enjoy. The gameplay is great, nice visuals, and as an MSI you know you're getting good quality. It does run a little hot, but that is to be expected from any gaming laptop or computer. At the very least, it acts as a nice heating element when I'm cold and using it. I'll keep coming back to MSI's as my laptop of choice.
