I recently purchased a Gamesir Nova 2 lite from China website sunsky. I am from India. I got the controller for about 15$ excluding shipping charges. My questions are as follows,

Saler didn't send Case, Cable and USB dongle with it. Is this saler official?
If I want to purchase a USB dongle from where I can purchase it?
Will I get a warranty for this product?
How to find the manufactured date of this product? I just discovered that many reviews about Nova 2 lite talk about RT keys get broken due to some design flaw. Most of the posts were older than 6 months, so wanted to know if Gamesir has fixed this and i got the controller which is manufactured after a fixed date hopefully.

Thank you in advance.
