Review: Love it - 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.
Review: Strong Gaming Performance - I bought this to replace my old home-built gaming PC, which was starting to show its age after eight years of constant use and a couple of hardware upgrades. I'm very happy with the purchase overall. This laptop feels well-built (and is surprisingly heavy) and runs all of my games (mainly MMOs) at high-to-max graphic settings with around 90-100 fps. I was a little dismayed by how fast the battery drained after I unplugged it from the power adapter, but to be fair I was running two monitors and a fairly graphics-intense game with everything maxed. I have nothing bad to say. Well, the documentation was pretty sparse; for example, the programmable backlighted keys are controlled by software and it took me a frustrating ten minutes to figure that out for myself. Maybe that's something I should have just known. This was offered at a good price with a couple of nice upgrades (64 Gigs RAM and a 2TB SSD) for around $300 less than other machines I was looking at with the same specs.

### ⭐⭐⭐⭐⭐ Slices the competition
*by S***M on September 20, 2025*

Love this laptop! Never had any issues with overheating, use it almost everyday. Was getting solid frames even in modern games like the BF6 demo. Like any gaming laptop you are going to have to keep it plugged in or it will brain battery pretty fast, but can last a quick gaming session in a pinch. The 240hz display looks awesome. I have had several MSI laptops over the years and they are always great!
