I am a programmer and frequently switch between my PC and Mac during the day. I have been using two keyboards for the longest time so the ability to connect this keyboard to my Mac or my PC with a simple switch is amazing and has given me so much desk space back.
The extra key covers it comes with are very useful - left of my space bar I have my windows-style key covers and on the right I have my Mac key covers. Brilliant.
Keyboard itself is very nice to type on, nicly solid and appears well made. I am very impressed by the value of the product, especially at the price offered here. The 96% layout is great, but will take a bit of adjusting to if you're used to full-sized keyboards.
No hesitation in recommending the keyboard, or the company.

The keyboard is fantastic physically. It looks great, feels very nice, and even the rgb lights are surprisingly funky.
It loses a star because I had to do some arcane hackery to get it to work properly under Linux. I feel that for the price they should be able to update their firmware to get their keyboard to work across platforms.

I never really understood why people spent money on premium keyboards; I've always budgeted £20-30, and was happy with what I'd got. My work gave me a stipend to get a more expensive one, and after a bit of YouTubing I chose this.
Now I understand. The feel of the keys is out of this world; the texture, the weight, it's like typing on piano keys, but that analogy doesn't do it justice. The sound is SO satisfying; like an old school typewriter but even better.
I can't speak highly enough of this keyboard, I love it.
Zero complaints about the service either: delivered promptly, and as described.

Amazing keyboard. I can use it between my windows pc and ipad through Bluetooth. Keypad helps date entry. Awesome aluminium frame. Very good rgb lights.

Its a great keyboard that feels like a dream. I was looking around alot at different options and wasn't sure this would be quality. However its sturdy, feels solid and has a nice finishes with the textures and lights.

The service I got from the Keyboard Company was fantastic and they emailed me at all stages - receiving my order, at dispatch, and emails if I needed help.
The keyboard is great! I kept the stock keycaps and switches. I installed some O-rings to dampen the sound a bit - but that was my preference. Love the weight of this as it is definitely hefty and feels really premium. Its much cheaper than the other options I have seen for the 96% layout and one of the only ones that have the availability for UK ISO.
Really happy with my purchase.

I live in the ROI, I ordered the item and it arrived within days, excellent service.
The Keyboard it's self is fantastic. I use it to manage two PCs, the ability to switch between the two using the preset Bluetooth options is brilliant, fast and without fault.
The typing experience is just what I like, not too much click but just enough to be satisfying. It is responsive and smooth.
The Aluminium version is definitely the way to go as the weight makes it feel extra premium.
The build is solid and sleek with no imperfections.
I 100% need the numpad so I didn't get the smaller version but I think this one is compact enough for any desk. The two feet settings is a definite bonus. I have already recommended this keyboard to friends and colleagues.
The RGB is also a very nice touch for late evenings, at first I wasn't a fan of the colours and stuck to the white light, but then the colours grew on me a little and now I have fun using the easy switch button included.
I highly recommend.
