    Great product
  

*by D***N on Reviewed in India on 11 August 2024*

It's an amazing product, the only thing is that the sound could've been a little better. Overall a go to product.

### ⭐⭐⭐⭐ 







  
  
    Good product under the optical switch category
  

*by C***E on Reviewed in India on 7 May 2024*

My review for the product is 4/5,It weighs of about 958 grams with the cable and 910 grams the keyboard alone.It's very good in terms of swapping comfort, it's easy.In terms of the RGB and colour combination it provides more than 20 lighting modes it's just too good.In terms of double click issue i didn't encountered any problem but it's very sensitive to small changes in the key switch and reflection on the screen hence makes good option for fast paced games like apex legends.

### ⭐⭐⭐⭐
