If you are looking for hardware wallet, IMHO, Trezor is best. I got it using expressed shipping, and there was no extra charges in customs or tax etc.
How did you get it without duty? Did it come through the post office?
He was just lucky that the customs were clumsy while checking out his package else they would have tagged it as worth a lot and would have demanded a fortune. It all depends of vigilance of the customs. Yes, it usually comes by Bhartiya Daak after getting released by Customs.
