Review: Excellent device - Thanks to this device my son can now beat grief and it is definitely worth it. I bought this for my son thinking what is this, but he loves it and is helping him beat many levels
Review: Very cool little device! - 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.

### ⭐⭐⭐⭐⭐ BEST POSSIBLE GEOMETRY DASH TOOL
*by J***H on 3 January 2026*

it cannot be understated how good this little device is for geometry dash.I’ve used the Apex pro, the huntsman v3 black analog, the g502 and this thing performs massively better with significantly less input delay. If you want to perform at your best possible level, don’t spring for a £200 keyboard because this thing does just as much good for a fraction of the cost.
