I brought a used razer blade stealth laptop from my colleague. He said it wasn't that bad, but it overheats easily and CPU is almost always forced down clocked because of it. So it didn't achieve the performance he expected from the spec. Razer Blade Stealth is almost perfect in spec. Built-in 4K display with NO NVIDIA GPU. That's great for the linux. Unfortunately, it's too thin. Not only it's bad for overheating, it doesn't have many useful ports. Especially the Ethernet. I can't understand why the computer, advertised as the gaming laptop, doesn't have Ethernet. I don't use it long enough to evaluate it, but so far, it's good for a portable toy computer.
