The media could not be loaded. Extremely satisfying to use. Even when I am not playing geometry dash with it, I use it. I have the dial set to volume up/down and escape. I have even set customized profiles for different applications and set different RGB profiles with them so I can differentiate keybinds with ease. I haven't done this, but you can even set multiple keys to activate at once, all in one keypress. Could be helpful for frequently used shortcuts. COOL NOTE: If you have a tempered glass side panel on your PC, ensure it is clean, along with the bottom of your sayo (the silicone feet pads), and stick it to the glass (literally zero adhesive, only the feet pads). This is so satisfying and holds up really REALLY well. No joke, when I remove it from the glass, it sometimes pulls the PC with it. This is how I have stored my sayo when not in use. It has stayed up for literal months with zero problem. In this configuration, I have a volume knob on the side of my PC case which I use ALL THE TIME. NGL, I think I would have gotten it just for the volume function.

The media could not be loaded. I was astounded by the seamless integration and exceptional responsiveness this device offers. The tactile feedback from the keys is unparalleled, delivering an immersive gaming experience that elevates precision and speed to new heights. One of the standout features of the Sayo is its harmonious fusion of ergonomic design and technological prowess. The keys exhibit an exquisite smoothness in their operation, affording a fluidity that significantly enhances gameplay. Each press resonates with an almost orchestral harmony, effortlessly translating my intentions into swift and accurate actions within Osu. Furthermore, the device's engineering precision extends beyond mere functionality; it encapsulates a symphony of innovation and craftsmanship. The attention to detail in the construction of the keys ensures durability without compromising on the whisper-soft keystrokes that create an auditory sensation akin to a maestro's gentle touch on the keys of a grand piano. Overall I would give it a 10/10.

My 16yr old loves it. He’s pretty rough on things and this has strong, great quality for the price. It’s comfortable for him to use and the perfect size and weight to fit on his desk. There’s also options to change the keys on there, so that’s cool. The keypad is good and spaced normal. It works great because he hasn’t complained about anything lol. It has a USB-C cord to hook up to the computer, I guess. No bluetooth.

The media could not be loaded. It sounds very clean and I use it to play geometry dash and it’s just very smooth with the 8k polling rate and 0 input delay. Very good product. The only downside is that if you click it too hard the key will sound bad but it will fix itself so that’s good.
