The Razer Boomslang 20th Anniversary Edition is a celebration of where it all started for Razer. It takes the company's first gaming mouse design and, 20 years on, packs it with the latest cutting-edge tech to create what should be an ultra-desirable collectors' edition. However, Razer then put a price on it. Never one to shy away from an aspirational price, Razer has gone all out with the Razer Boomslang 20th Anniversary Edition. Despite not being built from solid gold, it costs an eye-watering $1,337. Or should I say cost, as all 1,337 of these limited edition mice are already sold out. Nonetheless, having tracked it down at Razer's booth at Dreamhack UK - where the $1m ESL One Dota 2 tournament is taking place - I had to give this truly bonkers new mouse a try.
