I bought this pen drive from flipkart.I am using it from one year. if you are looking for a pen drive within a range around 400 then it is a very good product for you.out of 16 GB you will get 14.9 GB.the speed is good.I am getting 4-6 MBPS.I get 5 year replacement warranty which none of the brand will offer you at this price point .it is very light weighted.
I like this product because it also having password locking system to protect your data.I will recommend everyone because it is a very good product
