Excellent, solid mechanical keyboard. 10/7/2018 1:32:53 PM

Pros: Solid construction, real metal and Cherry MX switches for all your mechanical switch needs.

Cons: Spacebar sometimes registers twice rather than once. Very rare occurrence, but still annoying.


After nine months, the keyboard randomly stopped working. No warning, nothing. I've had $10 keyboards last for fifteen years, but this mechanical, German-made keyboard lasts for nine months? A waste of money.

Best bang for the buck! 9/17/2018 3:22:07 PM

Pros: I just received this keyboard, and it has exceeded my expectations. The brown switches are smooth, with a crisp actuation. My previous keyboard feel squishy and clunky in comparison. I run linux, and I've had zero problems with installing this keyboard. The media and function keys for lighting worked right out of the box.

Although full sized, this keyboard is smaller than I expected. I appreciate the compact footprint. Everything feels solid and well-made. The aluminum backplate looks great, and Cougar included a braided USB cord. This keyboard has everything I need without extra bling or bloatware.

Cons: Buyers should know that this keyboard has red, and only red, LEDs. I knew that when I purchased this keyboard, and I'm quite happy with the color. Their are also only three options for the lights, off, dim, bright, and brighter. Pretty simple, and that's ok with me.

Overall Review: Great job Cougar.

Nice Keyboard, Good Price, No Support (no spare parts) 2/27/2017 4:55:20 PM

Pros: - Solid keyboard, as in hefty, metal, weighty.
- Nice adjustable LEDs backlight (but red only)
- Audio media keys work even in linux!

Cons: No spare parts available! Although this was a cheap keyboard considering it's cherry switches, I would at least expect some replacement parts. Cheery keys might last, but I'm bettin' the keys wear.

Overall Review: German Engineering, I'd like to introduce you to Real World Maintenance - obviously you've never met.

Pros: Perfect for touch typists
very fast compared to a membrane keyboard
LED lighting level's are easily controlled from the keyboard

Cons: A bit louder than I was expecting
Accidentally pressing the spacebar while typing pop's up a Windows cut'n'paste dialog (need to disable that)

piece of junk 8/13/2016 9:08:18 PM

Pros: none

Cons: this keyboard is even worse than my $10 Microsoft 2000 keyboard. When I hold "A,W,S,D" keys in games, I expected it keep sending turning signal. Most of time it didn't. it only worked once. I have to repeatedly press, release and press to sending commands. Just within a month, the left "Alt" key stopped working. Also the Windows key in locate on right side of space, different than others. Really inconvenient. I have thrown it in garbage bin and switched back my cheaper normal keyboard.

Worked great til it didnt. 7/23/2016 11:32:52 AM

Pros: Looks are nice, lights up fine.

Cons: Worked great and then a little over a month later it's not working. Tried on several desktop and the keyboard lights up, but none of the keys are working. The volume buttons seem to still work, however nothing else does. Too late for a return i guess, so not sure what I'm going to do with this keyboard now...

Overall Review: I wouldn't recommend this to anyone at this moment. I'll keep this review updated with the support process.

A no-frills keyboard. 6/26/2016 3:27:12 AM

Pros: As this is the first mechanical keyboard I've used in nearly two decades, I have no points of reference to which I can compare. Therefore, I will just give my first impressions.

Having spent the past week with this keyboard, I've noticed both my speed and accuracy increase dramatically. That, of course, is attributable to the Cherry MX switches that are used in hundreds of other keyboards and so is not exclusive to just this one.

Cons: The keys feel very wobbly atop the switches. Whether this is due to the keycaps, switches, or something else I cannot say.
The huge printed logo at the top cheapens the appearance. Also, at least for me, the red lighting on silver backplate is not an appealing combination.
The software, like the keyboard, is barebones.
The uneven light bleeding also makes it look like a low quality product.

Overall Review: This is a fine keyboard if you don't need 20 extra macro keys or fully-featured software. I know this review is mostly cons, but that's because the best features of the keyboard are due to the switches, and not Cougar which basically attached LEDs to the switches, threw them on a PCB and topped them with some plastic and aluminum.

Great keyboard! 6/2/2016 8:30:45 PM

Pros: This is the first mechanical keyboard that I have owned, but I've used others. I love everything about it. Not just the fact that it is at a very good price point for a quality mechanical keyboard with Cherry switches - but the style, look, features and everything are great. I don't know how I lived without it. I couldn't go back. The bar has been raised.

Cons: Nothing yet.

Overall Review: I like this thing so much that I would say that if it (suddenly) falls apart after two years, I'd feel like I got my money's worth and I'd buy another one. That's not going to happen. I'll probably spill beer in it before it even comes close to wearing out. Even if I do that, it looks like the way that it is designed, the beer would mostly just roll off instead of acting as a beer catchment the way that some of my previous keyboards have.
