Yeah I purchased this product from amazon at 4000 rupees 5 months before.Still I didn’t come up with any errors with this, it also excellent in transmitting data.I used to copy all English series from my laptop to hard disk, it gets copied within minutes when I connect to USB 3.0 port.Cost may be high but you can better experience and I have to say one thing, please purchase any pouch for that.One of my friends used to give to his friends and it stopped working after it fallen 2-3 times.Its worthy product to buy: )
