### ⭐⭐⭐⭐⭐ Review
*by M***. on 9 February 2026*

My 13 year old son asked for this to play Geometry Dash on his laptop. I was sceptical but it is a really cool device with a little screen that he can customise with his own images/photos, I think he can change the colour of the lights under the keys and it also came with both black and white keys so he could choose which ones he liked best. I don't know much about it but it looks really good and he is very happy with the functionality.
