Cheap and usable: Amazon India Recommended Sellers Only→ This is not the best and everything starts to fall apart after multiple uses but it's more than enough if you just want to open laptops once in a while.
Have already recommended it to many people and for some little use, it's more than enough. The biggest problem is the thin guitar shaped thing that comes with it. It detoriates after only a few usage.

I can't believe how stupid Indians just gave it a five star review just for Rs.50. WTF! Are sharam karo haramiyooo... 600 ka samaan mein 50 mila toh 5 star daal diye.
Amazon India → Only one Seller and I am unsure about the seller.
However, the reviews say that this is pretty great.
DON'T USE ISO-PROPYL ALCHOHAL TO CLEAN THE DISPLAY. Only use Distilled Water and a micro-fibre cloth too.
