Took a chance...NOT disappointed
I’m not a huge keyboard enthusiast but I’ve owned my fair share of keyboards, especially mechanical ones. After my girlfriend took my K65 for herself, I decided to shop around. I own a Cooler Master MH650 so thought I’d see what they had to offer. There is virtually no wobble with the keys and the stabs come really lubed up. I got blue switches, my favorite, but they offer red and browns if you want linear and tactile without the loud click. I like the click to get back and annoy my girlfriend while I’m gaming for retribution for commandeering my other board but I digress…The knob is great. Easily programmable and makes a difference with how you use your board. I don’t think I can ever go back to a board without one after just using it for a day.The top plate is easily removable and it’s a cool little feature. Like seriously easy. Remove just some keycaps on the right side and pop a switch where the dongle is located and it pops right off. No screwing required. It’ll make cleaning easier after a few months. Sure, it’s kinda gimmicky, but in the future CM is apparently looking to offer different top plates for customization so I’m looking forward to what that’s gonna look like.All in all pretty satisfied and I’ll definitely keep an eye out for other CM offerings in the future.

Best keyboard I've ever had
I've been using mechanical keyboards for 10 years and this is my favorite by far. Kailh box white v2 switches feel better to type on than: Kailh box pale blue, Cherry mx blue/brown/red, or Gateron blue/brown. It's well worth $50

lightweight and small profile
It's a decent keyboard, not sure why they decided to go with a 60% keyboard rather than a full keyboard for a 30th anniversary, unique doesn't mean useful. I took a star off for the condition the keyboard arrived in, it had been knocked around enough in transit to dislodge most of the keys off the board, so I had to piece it back together.

DISGUSTING ABUSED KEYBOARD!!!
Absolutely abhorrent stench right out of thr box. I ordered this new and it came already opened and filled with spider eggs along with various other dirt and dust. There is HAIR in my crtl button even after using a air duster. Suprisingly it turns on but the light is very dim and shudders. I was scammed and i write this as a warning to anyone whos looking at this keyboard. DONT FALL FOR IT!!! Learn from my mistakes!

Sounds good
My first mechanical keyboard.After Logitech MX Keyboard really another feeling. It's more like toy, cool toy.But small, for me. I'd like 100% size, with numpad and etc... Using keyboard not for gaming.Build quality quite good. Included MX Cherry green switches no RGB, so if you going to replace red switches to another - buy RGB version.RGB backlight - really pleasant.so, my verdict - good keyboard, but I'd like to buy not 65%, not 75/TKL.. keyboard for my must be 100 full size. Cooler master - please make same keyboard, but full-size.

Construction feels more premium than its price!
Picked this up for 50% off and have been pleased with this keyboard for my use case. I used it as my daily driver for about 3 months. Personally used this board mostly for work and some casual gaming, so I didn't really explore much of the pre-programmed layers. Unfortunately, remapping with the proprietary Cooler Master program left a lot to be desired, as only specific keys could be remapped into keys from the same specific selection.As a piece of hardware, I think it's quite beautiful and looks/feels much more premium than the price point I paid. Its relatively hefty and sturdy. Additionally, changing the switches and keycaps was simple and the board remained stable while I was swapping switches and keycaps.Sound-wise, there is some minor metal pinging sounds from the top of the case, I think. I can't really eliminate all of it because of the "slide-on" mechanism to remove and replace the top case means some metal parts between the top case and the sliding mechanism will always touch. Sound from the board is otherwise quite pleasant due to the thick silicone layer included inside the board. I personally opted to open it up and apply a tape mod on the bottom of the PCB to further refine the sound of the board.I think the included stabilizers could've used some tuning and relubing because some of the stabilized keys had some rattle, but I couldn't really access or pull the stabilizers out very easily, so I just left them as-is.I think if you have basic needs and like a visually pleasing and pretty good sounding keyboard on a budget, I recommend picking this up on a sale. If you require remapping keys, I'd recommend looking for a different board.

Elegance incarnate
I'm not sure why exactly. It sounds a little over the top. Never thought I'd think of a keyboard as elegant, but elegant this is. That's the one word that just popped out when I started playing with it.Individually it's honestly nothing special. It's mechanical like all the other popular boards out there. It has a dial where a bunch of other keyboards have dials too. It's wireless with bluetooth and 2.4ghz (nice touch), but other keyboards have that as well. Even price wise it's not like it's a steal or anything.Just 100% it's the sum of its parts and how it's put together that makes me feel like this is the best keyboard I've ever used, hands down. I'm looking forward to adding some mileage to this baby.

Very Nice and compact.
Currently writing this review with the keyboard. I really like the compact design. The keyboard has a nice weight and premium materials. Typing feels nice, the control knob is a nice touch with multiple uses besides volume control. Great price too if you want to dip your toes into hot-swappable keyboards from a top brand.
