Only one.
I've harvested about 5-6 for switches.
In India, CHEAP is popular, at an given point of time, the cheapest option is the most popular.
In mech boards, it is between TVS gold and Razer BW. TVS Gold is popular for it's durability (vs other cheap keyboards), Razer BW is popualr as Razer is the most popular gaming peripherals brand in India and the only one readily available. The QFR is also avaialble, but pople tend to think, why would I pay about the same price for a smaller keyboard, and not backlit too.
