The premium gaming mouse be quiet! Dark Perk Ergo is either the company’s first gaming mouse or among its first serious entries into the category. From the outset, it feels significantly less controversial than the Light Mount keyboard. In comparison, that almost makes the mouse seem understated. At the same time, it is considerably more versatile. And in several areas, the design is genuinely impressive – something that is not often said about gaming mice, considering how mature and saturated the market has become. At first glance, it may seem that most meaningful innovations in this segment have already been explored.

Price and positioning
At the same time, the Dark Perk Ergo would likely struggle to attract attention without offering a few distinctive ideas of its own. The mouse is priced at around $120, placing it firmly in the premium segment. As seen previously with the Light Mount keyboard, products from be quiet! that exceed typical pricing expectations usually attempt to justify that cost through design choices, build quality, or additional functionality.
Package contents
Starting with the package contents, the box includes the mouse itself, a nearly 2-meter USB-A to USB-C cable with orange braided sleeving, a USB Type-C to Type-A adapter, a wireless USB-A receiver, a set of replacement PTFE glide feet, and the user documentation. To be honest, the package is more complete than expected – particularly the inclusion of spare glide feet, which are not always provided even in this price category.
In terms of design, there are several key points worth mentioning immediately. First, the mouse does not include RGB lighting. Second, the USB receiver cannot be stored inside the корпус. Third, Bluetooth connectivity is absent – the mouse supports only wired operation and a 2.4 GHz wireless connection.
And fourth, at a price point of around 6,000 UAH, the inclusion of a charging dock would not have seemed unreasonable. There are competing mice at noticeably lower prices that already include a dock as part of the standard package.
Key advantages
Now to the positive aspects – and there are more of them. First, be quiet! explains the absence of an internal storage slot for the 2.4 GHz receiver by using a partially skeletonized internal structure. This helps reduce the mouse’s weight to just 55 grams. That said, while the mouse is very light, it is not the lightest model on the market, as there are competitors with even lower weight figures.
However, this still places it firmly in the category of ultra-light gaming mice, which is an important advantage for many users. It is also worth remembering that the mouse is fully wireless and battery-powered, while still supporting wired operation and charging simultaneously during use.
The battery capacity itself is not disclosed. However, the manufacturer claims up to 110 hours of continuous operation, which translates to roughly 22 days assuming around five hours of daily use. It is important to note that this figure applies to the standard 1000 Hz polling mode, corresponding to a 1 ms response rate. The mouse also supports an 8000 Hz mode, reducing latency to below 0.2 ms, although this typically results in higher power consumption.
be quiet! Dark Perk Ergo Hardware
So where does this level of performance come from? The Dark Perk Ergo uses the PixArt PAW3950 sensor. Technically, it is not the flagship version of the series, as that status is typically associated with the PAW3950 MAX or PAW3950 Ultra variants. However, the MAX and Ultra models are essentially selected and additionally calibrated versions of the standard PAW3950, offering only marginally improved specifications. In practice, those differences are likely to be noticeable only to a very small group of highly competitive esports players.
In other respects, the PAW3950 can be considered a flagship-class sensor for modern gaming mice. It offers a maximum DPI of up to 32,000, a lift-off distance in the range of 1–2 mm, and a maximum acceleration of 50 G. The primary buttons use Omron Optical D2FP-FN2 switches, while the scroll wheel is based on a TTC Yellow encoder. Wireless 2.4 GHz data transmission is handled by the Nordic nRF54H20 microcontroller.
Software
Looking for more advantages? The be quiet! IO Center software is also part of the package. One limitation is that firmware updates require a wired connection to the mouse, which may be inconvenient for some users. On the positive side, beyond this restriction, the software is generally well-structured and stable, covering the essential configuration options without unnecessary complexity.
It is available in both online and offline versions and provides basic and advanced configuration options, which are stored in the mouse’s onboard memory. It is compatible with both the Dark Perk Ergo and keyboards. Therefore, I expect IO Center to be compatible with the entire be quiet! product ecosystem, including coolers and cases.
Experience using be quiet! Dark Perk Ergo
If you’re interested in real-world usage, my impression here is fairly straightforward. The mouse performs well overall. It is lightweight, and the plastic surface does not attract fingerprints. The buttons feel reliable, and the scroll wheel is responsive. One detail that stood out is the cable design: it is slightly raised at the base, which prevents it from rubbing against the mouse pad. This is a simple but practical design decision that improves everyday use, even if it is not immediately obvious in specifications.
The mouse body is not perfectly symmetrical. The side buttons are only located on the left side, and the rear part of the shell is slightly – though noticeably – shifted toward the left. There is also a subtle asymmetry on the lower section. As for the sound of the switches, it is better to evaluate it directly from the recording.
Summary
This model may appear somewhat plain and unremarkable, especially considering its price category. However, the combination of low weight, strong battery life, well-developed software, and near high-end performance, along with a few less common features, makes it a potentially interesting option for a wide range of gamers. Overall, I would consider be quiet! Dark Perk Ergo a reasonable choice, depending on individual preferences and priorities.
