What you are looking at on that page is in fact a fake, because Razer makes a Goliathius mouse mat - the famous extended one that most people know about that is sadly too green for your setup - and they also make a mantis mouse mat but they do not mix and match their product names.
However, I took the courtesy of finding you a nice rosewill mat that should work well. I hope this works for ya
I may have found the best gaming monitor for under $200. I'm currently using a dual monitor setup of the Asus VS278Q, and I love 'em. They're 27", full 1080p, a 60Hz refresh rate, and a 1ms response time to boot. Can anyone else find some great monitors for under $200?
