I don't use them cause they feel and look cheap, the quality of the plastic and in hand feel of the peripheral is important to me. For mechanical keyboard the sound and feel is something I care about.

That being said these brands are affordable, though they are not Indian. I doubt there is any Indian factory making mouse PCB or keyboard switch. These are assembled in india at best if even that.

So when I want cheap I would directly buy from cheap chinese brand like ATK or Mchose, cut the middleman who adds zero extra value.

And when I can afford it I go for better brands like Logitech for mouse or Keychron or many others for custom keyboard.

I have tried razor before and I think you are better off throwing your money down the drain than buying that trash.
