I have not been successful in locating suitable substitutes for this keyboard. Therefore, I decided to purchase it. There was a model from 2022 that was used before, and if the cat hadn't gotten wet, that model would have been used. In my opinion, the most recent one was superior. After adding two photos and purchasing a led-usb tape with a brightness setting of up to 300, I am now able to see the top buttons more clearly. Due to the fact that they are not divided into smaller groups, it is difficult to click on the correct one when doing so blindly; you will need to look closely. LED illumination is a significant improvement.
