With the SKILLER SGK50 S3 Ultimate Rev2, Sharkoon is launching a revised version of its 75 percent keyboard, which is clearly aimed at design and custom keyboard fans. The set combines a mechanical gaming keyboard with a matching mouse pad in ocean design and relies on high-quality PBT keycaps, its own linear switches and hot-swap support. The package thus combines an eye-catching look with features that are otherwise more likely to be found in the enthusiast niche.
- 75-% layout with nautical ocean design including matching mouse mat included.
- Dye sub-PBT keycaps, linear Sharkoon switches and hot-swappable PCB for individual tuning.
- Polycarbonate plate, double-layer silicone damping and pre-greased stabilizers for optimized sound.
- Fully customizable thanks to VIA and QMK support, RRP is 99.90 euros.
Compact layout with coordinated ocean design
The SKILLER SGK50 S3 Ultimate Rev2 relies on a compact 75 percent layout with around 84 to 85 keys (ANSI/ISO), which retains the arrow keys and function row without taking up as much space as a full-size keyboard. The housing measures around 310 x 120 x 40 millimeters and weighs just under 800 grams without cable, which ensures a stable stand. The eye-catching Ocean design catches the eye: the multi-colored PBT keycaps in shades of blue and turquoise are labeled using the dye-sub process and are therefore particularly resistant to abrasion and fingerprints. The set includes a color-coordinated mouse mat, which extends the maritime motif beyond the keyboard to the entire workspace and gives the desk a consistent look.

Despite the focus on design, functionality is not neglected. The keyboard features RGB lighting with various effects that can be addressed via a button and customized to personal taste. A detachable, textile-covered USB-C to USB-A cable in spiral style makes transportation easier and blends in with the overall look. Technically, the SKILLER SGK50 S3 Ultimate Rev2 offers a polling rate of 1,000 Hz, N-key rollover and anti-ghosting, which means that even fast inputs in shooters or MOBAs are reliably captured. In addition to Windows PCs, compatibility also extends to current consoles such as PlayStation 4 and 5, which further expands the range of applications.
Linear switches, hot-swap and fine-tuning via VIA/QMK
At the heart of the Ultimate Rev2 are specially developed Sharkoon linear switches, which offer a soft, even typing feel without a noticeable pressure point and, according to the manufacturer, are specified with an actuating force of around 41 grams and at least 50 million keystrokes. Sharkoon has thus clearly positioned the keyboard in the gaming sector without sacrificing a precise typing feel. The special feature of the series is retained: The PCB is hot-swappable and accepts 3-pin or 5-pin switches in standard design, so that switches can be swapped for other mechanical models without soldering. This is an important plus point for fans of custom keyboards, as the characteristics, noise profile and feel can be subsequently adapted.
To optimize the sound, a polycarbonate positioning plate is used inside, combined with two-layer silicone damping and pre-greased stabilizers for larger keys such as the space bar or Enter. This combination is intended to reduce resonances and enable a muffled, “thocky” sound, as is often preferred in the scene. In addition, the keyboard comes with 256 KB of onboard memory to save profiles locally, which is particularly interesting in conjunction with support for the open source firmware VIA and QMK. These tools can be used to customize key assignments, macros, layers and lighting down to the last detail without having to rely on proprietary software – a feature that is rarely found in this price range.
The key technical data of the keyboard can be summarized as follows:
| Feature | Specification |
|---|---|
| Layout | 75%, 84 ANSI / 85 ISO |
| Switches | Sharkoon Linear, hot-swappable |
| Keycaps | Dye-Sub-PBT, Ocean design |
| Lighting | Per-key RGB, customizable effects |
| Polling rate | 1,000 Hz |
| Onboard memory | 256 KB |
| Software support | VIA & QMK |
| Dimensions (L x W x H) | approx. 310 x 120 x 40 mm |
| Weight (without cable) | approx. 796 g |
Price, availability and classification
According to the manufacturer, the Sharkoon SKILLER SGK50 S3 Ultimate Rev2 is available immediately at a recommended retail price of 99.90 euros, including the matching mouse mat in ocean design. The first retailers are listing the set in this price region, which seems plausible in view of the PBT keycaps, proprietary switch design, hot-swap PCB and VIA/QMK support. This positions the keyboard well above simple entry-level boards, but remains below the price level of many enthusiast models with similar features.
For users looking for a compact layout, eye-catching design and extensive modding options, the SKILLER SGK50 S3 Ultimate Rev2 offers a well-rounded overall package that stands out from the crowd of classic gaming keyboards both visually and technically
