I bought 1 16gb and 1 8gb sandisk pendrive 6months ago and I found that this is the best pendrive I have ever used. From 6 months there is no problem with both pendrives. Both are working properly. The write speed is also good when copying something from laptop. Also the 16gb pendrive has a port to connect to mobiles also. The body of the pendrive is of good quality plastic so it doesnt breaks on rough handling. Overall a good pendrive brand.
