Love the cable, it has a super high production quality and matches my keycap set perfectly. This was the best option for matching to GMK Dracula, it looks fantastic!

Exceptional product of the highest quality, speedy delivery, and excellent communication. Highly recommended, and I will definitely be using again!

This is my 3rd Kool Keys cable. It's absolutely gorgeous and a perfect color match and David's customer service is fantastic and shipping was very fast even though I'm in the United States and pls send help I can't stop buying cables

(spoiler: not gonna stop buying cables)

Gorgeous and subtle cable. Packed very nicely. Clearly a lot of love and experience was put into this. Instantly ordered 2 more when I recived it..

I know it may seem weird to say that a 75 dollar cable is a “good value”,but compared to other custom cables this is on the cheaper side in my opinion, and at the absolute top for quality. it is truly immaculate. Perfect coatings, perfect jackets, perfect heat shrink. amazing QC.

High quality materials, great colors. Will definitely be back to buy more!

Amazing from the customer service to the end product. I can't wait to order more.

This hyperbeige cable ls perfectly matched with the set. I expected (and received) an amazing color matched cable, but what I didn't expect was how fast shipping would be from the UK to the southwestern US. 4 days from clicking buy to receiving the cable for an international shipment is insane. I also realized this next part only after purchasing my first cable is that the owner of koolkeys is pretty involved with the keyboard community online, and it was really cool to see how generally positive and helpful they are. The cable sells itself, but everything else ensured that I won't be looking anywhere else for my cables!

Brilliant cable with beautiful sleeving and connectors. Matches well with my setup. Delivered really quickly after ordering. Thank you Kool Keys

Absolutely love this cable. The color matching is spot on and pairs perfectly with my GMK Dracula setup. You can tell a lot of care went into the details and the overall build quality. It feels super premium and looks even better in person.

Also have to shout out David, he’s great. Super responsive, helpful, and clearly cares about the product and the customer experience.

Would 100% recommend and will be buying again.

David really cares about the quality of the cables he makes and is fantastic with communication. If you have any questions or doubts about doing a fully custom cable from scratch just read the info on the site and reach out to him with specifics and you will get a great result!

The brass sleeving looks fantastic and is very cat resistant I highly recommend it.

Awesome cable and crazy fast shipping from the UK to the US. Like 4 days fast with 2 of the days being weekend days! The color matching is impeccable.

These cables aren't cheap but they make a great finishing touch for your keyboard. It's a great color match with the GMK botanical keycaps. If you're building a custom keyboard, you probably care about the details so I don't need to preach to the choir. I signed up for the restock notification and when I got the email that it was back in stock it was a no-brainer.

These are really fantastic cables. I've spent a lot on custom Hart Audio cables in the past so have some familiarity with cabling. Although these are USB and use different terminations, the quality is way, way up there. The ceramic coating is perfectly applied and the colors spot on. Shipping time from overseas was pretty quick as well. Well worth the money to match a GMK set!

could not be happier with my Blackout and MM Concrete cables!

The cables look amazing and the service was great! Even though I wasn't able to configure the cable exactly as I wanted through the config page, David was super quick in showing me the options I had!
