Modders-Inc posted a video review on the Cougar Attack X3 RGB Speedy Keyboard
A quote from the article:
Cougar has updated their line of Attack X3 mechanical keyboards for 2018, and the introduction of the Speedy will be met with quite a bit of excitement. The Attack X3 RGB Speedy retains much of what made it a popular keyboard for the past couple years. The aluminum backplate, solid construction, excellent build quality, and of course, per-key RGB backlighting.Cougar Attack X3 RGB Speedy Video Review
The build quality of the Cougar Attack X3 RGB Speedy overall is excellent, and I’m digging the Speed switches quite a bit more than I thought I would. I’m personally not a fan of Red switches or linear switches in general, so I wasn’t expecting much out of this keyboard. I couldn’t have been more wrong. The new Speed Silvers are a joy to both game and type on. One of my biggest gripes with the reds is the low actuation force required caused me to be sloppy when doing anything besides gaming. I’m not sure what the difference was on the Attack X3 Speedy, as on paper these should be very similar, but I was much more accurate on this board than I expected.
