    With the SKILLER SGM25W, the SKILLER SGM70W, and the FIREGLIDER One, Sharkoon expands its gaming mouse portfolio across several price and performance classes. Although all three models at first glance follow a similar design language and can each be operated as dual-mode mice, both wired and wirelessly, they are aimed at different target groups. While the SKILLER SGM25W is designed as a lightweight all-rounder for ambitious players, Sharkoon positions the SKILLER SGM70W clearly in the e-sports segment. Here, more modern sensor technology, significantly higher polling rates, and a further reduced form factor are used. The FIREGLIDER One, in turn, revives the long-established FireGlider name and reinterprets the concept completely as a modern, ultralight gaming mouse.

    All three models share a focus on low weight, a wireless 2.4 GHz connection, USB-C charging, and optical PixArt sensors. The differences lie primarily in sensor performance, polling rate, battery life, weight, switch technology, and the respective target group. For this test report, all three models are compared in terms of build quality, ergonomics, sensor performance, latency, software, battery life, and practical suitability. This makes it possible to assess which mouse is the most sensible choice for which use case.

    Sharkoon uses a modern dual-mode concept for all three mice. All models can be used both via the included USB-C cable and wirelessly via a 2.4 GHz radio connection. This allows continued play during charging without interruption. All three mice also feature integrated profile storage, PTFE glide feet, and optical PixArt sensors. Configuration is done via software or directly on the mouse, depending on the model. The maximum wireless range is specified by the manufacturer as up to ten meters. But let’s start from the beginning 🙂

    Introduction & Unboxing

    Sharkoon uses a consistent packaging concept for all three models with a modern and deliberately minimalist design. The front is dominated almost entirely by a stylized mouse graphic, while the respective model name is highlighted prominently in white with strong contrast. This allows the individual models to be distinguished from one another at a glance. Sharkoon also differentiates the mice by color. The SKILLER SGM25W appears in dark gray, the SKILLER SGM70W has a slightly violet or gray-looking coloration, and the FIREGLIDER One White Edition uses dark gray packaging with an additional note about the White Edition. The overall design looks clean and completely dispenses with eye-catching graphics or marketing elements.

    The back of all three packages focuses on the most important technical features and the scope of delivery. All information is printed in multiple languages and divided into separate language sections. This keeps the layout clear despite the amount of information. In addition to the technical key data, the sensor, DPI range, polling rate, connection options, and the contents of the package are listed. A barcode, model designation, and manufacturer information are also located on the underside of the packaging.

    Personally, I do not like the packaging that much. Somehow it feels a bit loveless. The mice are wrapped in paper, and the accessories are just tucked in at the sides. Yes, of course, the packaging is not the main point, and given the very good price, that can be overlooked. After all, the contents are what matter. I only did not want to leave that unmentioned here. All good!

    Sharkoon SGM25W

    The Sharkoon SKILLER SGM25W uses a deliberately simple and functional design. The top is finished entirely in matte black, which conveys a high-quality impression and appears largely resistant to fingerprints. The symmetrical basic shape with gently rounded contours is striking, making the mouse suitable for palm, claw, and fingertip grip alike. The rubberized mouse wheel has a fine texture and provides good grip when scrolling. Between the two main buttons there is a discreet status LED, while the Sharkoon logo in the rear area completes the otherwise restrained look.

    All important controls and technical components are located on the underside. The optical sensor sits in the center and is supplemented by a separate DPI switch. Next to it is the slide switch for changing between 2.4 GHz wireless mode and the off state. At the rear, there is an integrated compartment for the USB receiver so that it can be safely stored during transport. Fairly small PTFE glide feet ensure smooth movement on different mouse pads. Overall, the underside appears cleanly processed and designed with practicality in mind.

    The RGB lighting is pleasant and fits well into the overall appearance.

    Sharkoon SGM70W

    The Sharkoon SKILLER SGM70W presents itself with a modern, understated design and is aimed at users who value the lowest possible weight and an ergonomic shape. The matte surface looks high-quality, offers good grip, and is also not very susceptible to fingerprints. The rubberized mouse wheel engages cleanly and precisely, while the main buttons have generous spacing and allow for a comfortable finger rest. Overall, the SGM70W leaves a very tidy and high-quality impression that is convincing both in gaming and in everyday work.

    The underside is functionally arranged and houses the optical sensor, the DPI/polling-rate switch, and the power switch. Striking are the large glass glide feet, which offer particularly low friction compared with classic PTFE skates and ensure exceptionally smooth gliding. The USB receiver can be safely transported in the integrated storage compartment. Overall, the underside is cleanly processed and designed for maximum performance as well as high everyday practicality.

    There are also PTFE skates included in the set. I think that is good. I was very curious about the glass feet. They look very high-quality. One thing I noticed here: the feet are so smooth that the mouse almost moves by itself. These are the smoothest feet I have personally seen so far. If that is what you are looking for, this is the right place. In addition, they will not lose their quality. Mouse pad/desk mat with these feet, strongly recommended.

    Sharkoon Firegilder One – White Edition

    The Sharkoon FireGlider One White Edition uses a simple, modern design with a completely white housing surface. Its symmetrical shape makes it suitable for both right- and left-handed users and it sits comfortably in the hand. The clearly separated main buttons, the grippy mouse wheel, and the matte surface convey a high-quality impression. Overall, the mouse appears compact, light, and designed for precise control in everyday use as well as during gaming.

    On the underside are the optical sensor, a separate DPI switch, and the power on/off switch. The large-area PTFE glide feet ensure smooth and low-friction gliding on different mouse pads. Also integrated is a practical storage compartment for the 2.4 GHz USB receiver, which allows it to be safely stored during transport. The clean layout of the underside underlines the thoughtful and functional overall impression of the FireGlider One White Edition.
