Price to performance ratio is very good. ### ⭐⭐⭐⭐⭐ Perfect *by S***N on 25 December 2025* Perfect, brought for my son who is addicted to geomatry dash and is on the extreme demon levels. He cannot believe what a difference this makes.. he struggled with the mouse but has got much further using this. Love the light up colour aswell. ### ⭐⭐⭐⭐⭐ Review from an all time mouse player *by G***L on 9 February 2026* I'm mostly used to using a low hz mouse for geometry dash. Never touched the arrow keys or space in my months of playing. Switching to this, it feels much smoother and things feel easier. I now realise my mouse was NOT as fast and smooth as I thought it was...If you're unsure about getting used to playing with a sayodevice, it's been about three hours now and I'm already used to it. I'm working on acu right now and had about 40 percent learned and I'm up to about 80 now. It's much easier to control (when you get the hang of it, may take a bit to feel comfortable). Experiment with grips too!! If you're scared of wasting money on something that you may not be comfortable with, I'm WAY more comfy playing with this now. All up to preferences though!!
