Pro The keyboard backlight is fully customizable
The keyboard backlighting can be fully customized using Razer's Synapse software. You can enable custom lighting patterns using colours or light intensity or even choose to light individual keys with a specific colour. This way you can for example make the light for the WASD keys blue while the rest of the keyboard is red.
Pro Great battery life for a gaming laptop
Even if it's the thinnest gaming laptop on the market, it has one of the largest batteries found on a laptop. This feature helps a lot with keeping a relatively high battery life which can go up to five hours even while gaming or doing similarly resource-intensive tasks.
Con Too expensive for what it offers as far as performance goes
As far as performance goes, the Razer Blade is virtually the same as most gaming laptops with these specs, however, the Razer Blade costs at least $500 more on average. You are mostly paying for the beautiful design, portability, and build quality.
