I agree with BlueBar. Razer, imo, has bad build quality and quality assurance. Their products might look really cool and innovative, but when you get one in your hands, it's sub par with other things you could've gotten.
I got one of their flagship mice once, and the right click took -10 grams to push down so I was always hitting it. Not related to keyboards, I know. But just saying I don't trust their workmanship. It might be good. Idk.
