Are there any alternatives?

The Razer Huntsman V2 is the most direct competitor thanks to its 8,000Hz polling rate.

　　I’d also recommend the Corsair K70 RGB TKL, though. It’s as much as $60 cheaper, and it doesn’t have a number pad taking up precious mouse space.

　　

How long will it last?

Cherry MX switches are rated for 60 million keystrokes, so the K70 RGB Pro could last as much as a decade or more. You’ll probably want to upgrade to a new keyboard before the switches give out.

　　

Should you buy it?

No, buy the Corsair K70 RGB TKL instead unless you absolutely need a number pad. The K70 RGB Pro isn’t a bad keyboard, but it’s not worth its asking price.
