### ⭐⭐⭐⭐⭐ Excellent performing keyboard
*by A***G on 4 July 2025*

It's a great keyboard with amazing build quality, nice lighting, and click feedback. Feels very stable even without any large mousepad due to its heavy weight (~800g) and decent grip at bottom. Switch and typing experience is good, the lighting presets are nice. Polling rate + anti ghosting = solid for gaming. All features are worth it if you are getting it for around 2200rs. But a few negatives.. The brightness of RGB is decent, not too bright. But still nice if you have a low light setup. And the switches feel too tight to remove with the puller. I have tried many times but they are just too tightly fitted to remove. Idk if it's with only my model although it's not necessary things so that's ok. Overall, it's perfect keyboard for the price. The negatives don't affect the usage of it so they aren't a major problem for me
