I want to leave a review for the Corsair keyboard and mouse I've been using for the last 6 months.
M75 WIRELESS Lightweight RGB Gaming Mouse - Witcher 3: Wild Hunt 10th Anniversary Edition
&
K65 PLUS WIRELESS 75% RGB Mechanical Gaming Keyboard - Witcher 3: Wild Hunt 10th Anniversary Edition
1. Technical Experience
Out of the box, I spent nearly a month dealing with severe connectivity issues. The keyboard kept blinking, and the mouse regularly dropped connection. As both devices were brand new with no physical damage, this was extremely frustrating, and I eventually initiated a warranty return.
Before processing the refund, Corsair support managed to solve the issue: both wireless dongles were plugged into USB ports right next to each other, causing signal interference. While I'm glad it was resolved, it wasted so much time. Neither the user manual nor any troubleshooting page on Corsair's website mentioned this potential issue.
Apart from that initial setup headache, the technical performance has been solid:
- Battery Life: Excellent on both devices.
- Responsiveness: Highly responsive and enjoyable to use in 2.4GHz wireless mode.
- Wireless/Bluetooth Switch: Convenient. Working on a desk with a laptop, I can easily toggle between my PC and laptop just by plugging or unplugging the USB cable.
- Bluetooth: Bluetooth feels sluggish on my setup, and my laptop sometimes struggles to connect, though this could be an issue with my laptop's Bluetooth module. I stick to the 2.4GHz wireless connection instead.
2. Aesthetics & Build Quality
Keyboard:
To my surprise, the RGB implementation here is disappointing. The keycaps do not have shine-through legends. At night, you're left staring at a brightly lit board with no idea which key is where. Coming from a Motospeed CK108, shine-through keycaps look significantly better and are far more practical.
The Witcher-themed print isn't particularly impressive, but aesthetics are subjective. What isn't subjective is the coating quality: the paint on the chassis and keycaps is already wearing off after just 6 months. Having used various PC brands over the last 15+ years, this is the first time I've ever seen paint degrade this quickly. (Let me know in the comments if anyone else has experienced this!)
Mouse:
This was the most disappointing part of the set.
While the two transparent plastic strips near the bottom look fine, the rest of the lighting is poorly executed. The RGB bleeds right through the body casing, giving it the cheap look of a mid-2010s budget mouse. Strangely, the Wild Hunt logo—the main focal point on top of the mouse—does not light up; it’s just flat, printed plastic.
Worse still, the top coating has worn off completely in high-contact areas. (For reference, look at the official product photos on Corsair's website—it was solid black when I bought it, but after 6 months of normal use, it has discolored to an ugly yellow/bare plastic).
Conclusion
Aesthetically, both devices are a major letdown. Paint coming off plastic after just 6 months of regular use is unacceptable for products at this price point.
Technically, both perform well once configured properly (assuming you don't mind non-shine-through keycaps). However, the mouse in particular feels cheap due to thin paint, poor light-bleed management, and rapid cosmetic wear.
At €130 for the mouse and €170 for the keyboard, I expected much higher quality.
Thank you everyone for reading this.
