Review: Amazing device with lots of utility - Item arrived on time as promised and works as described by the seller. Service is great. On my particular unit the screen was a bit buggy but seems to be working fine now. The keys need calibration often from what I've seen but still works amazingly well. Easy to use and to set up. You can customise the LED lights and the screen on the device which is very handy. The keys feel amazing and the utility of the buttons are great as well, as you are able to map them to any key on a regular keyboard on Windows, MacOS, and Linux. Absolutely amazing for the price.
Review: llegó en perfectas condiciones, realmente lo utilizo para jugar osu y es bastante cómodo.
