It is excellent flash drive I used ever. It take only very less time for booting and data transmission and also provide many other features such as Renaming drive default name, Quick format. SanDisk pendrives mostly available in plastic metal body is not available . Body of the pendrive is plastic but the plastic used is very high quality it can prevent the circuit board by rain and varying temperature. Overall performance is very good. I like it and also I recommends this for my followers.
