I bought my sandisk 16 gb otg pendrive from flipkart for 411rs. It is very useful as it can be connected to smartphone without the need of an otg cable. Its read and write speeds are awesome. It can easily be connected to computers and smartphones with otg connection except iphones. It is durable and it does not have any heating problems when connected to a device. Very good value for money at this price. It looks good and is very compact. Till now it doesn’t have any problems even though it has been used often.
