So far a great laptop. It's lighter and more powerful than my old Acer Predator and generates half the heat. The keyboard function keys are weird to get used to but you get used to it. The sleep function...this laptop does not like sleeping. It randomly wakes up for no reason lol Gaming, this laptop does what I bought it to do, and does it well. Again, with less heat than my previous laptops. The ports are all stiff and solid, which you want. USBs dont wiggle at all and dont randomly fall out. The buttons feel great to press, soothing for my autism. The wifi adapter on here is really strong, way stronger than my old laptop. The 4070 and Ryzen 9 combo are fantastic for pretty and intense games like Helldivers. NOTE: if you have trouble with the built in crosshair (which is usefull tbh), then go to the settings for it and disable the option allowing you to move it with cursor. Works wonders so your game stops switching to desktop.

The media could not be loaded. After a whole lot of research, I came to the decision that this was the best bang for my buck in terms of gaming laptops. I know a 4080 or a 4090 would have been better, and it could’ve used a bit more VRAM. But those laptops were easily at least $500 more and up, and it just didn’t seem worth it imo. And man, does it still do a great job. I’ve played almost every game at Ultra and Maximum settings with little to no issues. If running natively on the laptop screen, it’s buttery smooth. I am using a 34’’ curved monitor, and projecting to two screens at once at 3500 resolution, which can cause some games to lag a little at Ultra settings, but after some minor tweaks I can still run everything great! Overall, this laptop is a piece of art. It’s form is sleek and sexy, it’s relatively lightweight, the screen is great, it’s RGB keyboard looks awesome, and it’s just a total powerhouse, not to mention extremely affordable for what you’re getting. Incredibly happy with my purchase, one month in and I have no regrets. The speakers are nothing special, but the sound quality it outputs is clear. Also, I haven’t really tested out the battery, I hear it’s got a short lifespan, but I keep it plugged in so I don’t really notice. It does get REALLY hot though, and quite easily, even when just using Chrome I’ve clocked it at about 104 degrees Fahrenheit. If you’re thinking about getting this laptop, I would **highly recommend** getting a laptop cooling fan to sit underneath. There are some great brands for reasonable prices on Amazon. I purchased the Kevin Gaming Laptop Cooling Fan (I think that’s its name),, it can go up to 2,800 rpm and keeps my laptop at a nice 90-94 degrees.

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.

Good laptop. I bought the maxed out version with 64 gb of ram, a Ryzen 9, and a RTX4070 Very good components and parts. After 8 months of service I have not had any issues with hardware. I had to update the bios to fix some bugs that it came in out of the box but that was not a big deal. Materials are OK. A lot of plastic. It has a very good cooling system. Don’t expect a quiet laptop while gaming with this one. It performs very well. It runs tarkov in 2k at 70fps in streets.

Great quality for the price. Though it is fairly heavy, that's to be expected since it's larger than usual laptops. Works great, the design is sleek and clean, can run many great games. My only complaint is that the battery life is very short, however I personally always keep it plugged in anyways; it does produce a significant amount of heat, but this is not unexpected.
