### ⭐ I receive damage product  button  sometime works and sometime doesn't
*by F***D on 28 August 2023*

My keyboard was in very good condition but when i plug with my laptop i tried to check all the keys are working fine or not and i found that "\" this key is not working properly so i take it out and change the red key which is included in the box still problem is with the main board

### ⭐⭐⭐⭐⭐ Good product but didn't receive key puller please provide
*by S***  on 12 March 2023*

Awesome product, please proceed key cap puller

### ⭐⭐⭐ It's a good product but I buy it Renewed
*by V***V on 4 July 2023*

If you're scrolling comment to see it's a good product or not it's a good product. I buy it renewed so I get some problem like right alt key's rgb not working & sometime total rgb got shutdown for couple of minute. So I return it and then buy a new one. I'm not kidding it's a good product. Also if you wondering about the price, I bought renewed 1st (Rs. 1999/-) though I return it then buy a new one at Rs. 2649/- :)
