CoolKiller CK75 Transparent Mechanical Keyboard review rechargeable wireless gaming keyboard with RGB backlit

Description

Aesthetic and Build Quality: A Transparent Marvel

The CoolKiller CK75 Transparent Mechanical Keyboard immediately caught my attention with its sleek, transparent acrylic case. It’s one of those keyboards that not only feels premium but also looks like it belongs in a high-tech setup. The compact 75% design (80 keys) is a game-changer for desk space. I could keep my coffee mug, notebook, and even a small plant next to it without feeling cramped. Despite its compact size, it weighs a solid 3.61 pounds, giving it a sturdy, no-slip feel during intense typing or gaming sessions.

The south-facing RGB backlighting is stunning. It’s vibrant without being overbearing, and the customization options are endless. I found myself fiddling with the default RGB effects for a good hour because each one looked more mesmerizing than the last. If you’re a fan of personalizing your gear, the ability to DIY your RGB effects and key functions through the compatible programmer for Windows and Mac is a huge plus. Just remember, the programmer only runs in wired mode—a small detail that caught me off guard initially.

Typing and Gaming Experience: Smooth Like Butter

The gasket-mounted design is where this keyboard truly shines. The poron foam switch pads on the top and bottom edges create a typing experience that’s both soft and responsive. Paired with the Ice Tactile Switches, pressing each key felt satisfying, almost like a gentle pat on the back for my fingers. I used it for both work and a weekend gaming marathon, and it performed beautifully in both scenarios.

The KSA profile two-layered keycaps are another standout feature. They not only improve the typing angle but also add a tactile richness to the overall experience. Switching between gaming and typing felt seamless. Plus, the hot-swappable capability means you can swap out the switches without soldering. I tried installing a set of linear switches just to test this, and it was as simple as popping Legos into place.

Connectivity Options: Triple the Convenience

One of the biggest upsides of this keyboard is its tri-mode wireless connection. I tested it with the Type-C cable, the 2.4G wireless dongle, and Bluetooth 5.1. Switching between devices was surprisingly smooth, with no noticeable lag. The magnetic storage for the dongle is a thoughtful touch; not once did I worry about misplacing it.

Using Bluetooth, I connected it to my laptop, desktop, and even my tablet. For someone like me who’s constantly juggling devices, this feature is a lifesaver. The signal transmission was stable throughout, whether I was typing up a storm or engaging in a heated gaming session.

Battery Life and Rechargeability: All-Day Power

With a 3750mAh battery, this keyboard is a powerhouse. I turned on the RGB lighting at full brightness and managed to get a solid 25 hours of use. This is impressive, especially for a wireless keyboard with such vibrant lighting. Charging it via the Type-C cable was quick and hassle-free. I could use it in wired mode while it charged, which was incredibly convenient.

Key Benefits

• The transparent acrylic case and vibrant RGB lighting make for a visually stunning design.
• Tri-mode connectivity allows seamless switching between multiple devices.
• The gasket-mounted structure and Ice Tactile Switches deliver a smooth typing and gaming experience.
• Hot-swappable keys offer customization without soldering.
• Long-lasting 3750mAh battery supports extended use even with full lighting.

Areas of Concern

While the CK75 is a fantastic keyboard, there are a few shortcomings worth noting:

• The programming software only runs in wired mode, which could be inconvenient for some users.
• At 3.61 pounds, it’s not the most portable option for those who frequently travel.
• The keycap font design might not appeal to everyone; it’s a bit too bold for my taste.

Competing Products

When stacked against other mechanical keyboards like the Keychron K2 and the Razer BlackWidow V3 Mini, the CK75 holds its ground remarkably well. The Keychron K2 offers a similar tri-mode connectivity but lacks the gasket-mounted structure, making the typing experience less cushioned. Meanwhile, the Razer BlackWidow V3 Mini excels in RGB customization, but it falls short in battery life compared to the CK75.

Where the CK75 really pulls ahead is its hot-swappable capability, a feature neither of its competitors offers out of the box. However, if portability is your priority, the Keychron K2, with its lighter build, might be a better choice.

Value for Money

As someone who’s tested a fair share of keyboards, I’d say the CK75 offers excellent bang for the buck. Its combination of premium build quality, customizable RGB, and multi-device connectivity makes it a versatile choice. Considering its features, it’s a worthy investment for both gamers and professionals looking for a reliable, stylish keyboard.

This keyboard isn’t just a tool; it’s an experience. From the smooth gasket-mounted design to the vivid RGB lighting, it checks almost all the boxes. While it has minor flaws, they don’t overshadow the overall quality and performance.
