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.

[Oct 2024] We had an old laptop that died recently and wouldn't be worth repairing, so while the October Prime Days event was on I looked for something that should be somewhat 'future proof' with good specs at a price less than $1000. I picked the MSI Katana A15 AI 15.6” 144Hz FHD Gaming Laptop with the Ryzen 7-9945HS and NVIDIA Geforce RTX 4060, 32Gb RAM, and 1TB SSD. It was on sale for $879 plus tax at the time, which was a really good price for the specs. It has all the ports we need for plugging in different devices, the keyboard feels good, and the screen is bright & crisp with a 144Hz refresh rate that keeps up with the busiest action scenes in games and movies. The screen is a bit more 'letter box' shape than I'd really like, but that's the only thing I can find to whine about. It's a bit heavy compared to some, but that isn't an issue for us. It runs all our small business office and accounting software silently, without the cooling system kicking in at all. The only time it cools itself is when playing graphic intensive games, and IMHO the fan noise isn't bad at all. Most of the time it sits on a multi fan cooling pad, but even without that turned on the laptop never gets particularly hot. All in all, it was a great deal, so if it's on sale for less than $900 again, snap it up. Even at around $1050 I think it's still a worthy contender.

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.

Bought for Christmas gift for Grandson. He's enjoyed this so much. Battery does not last too long but charger works. Uses for online gaming. Screen size I'd good size and quality. Good sound. Works with headphones.

MSI delivers a very nice gaming laptop. The picture quality is beautiful and crisp. The refresh rate is very nice. My only complaint so far is that the AC adapter will not stay plugged in. I believe it is a flaw in the design. You literally cannot move it in the least without the AC adapter starting to slide out. If I wanted a desktop that never moves, I'd have bought a desktop. In under a month, I have sent it to the manufacturer to see if they can do anything to fix the fit. At least it is under warranty.
