I bought a Sandisk Cruzer pendrives 4 years ago from flipkart at good discount price the pendrive had good packing, then I just plugged the pendrive to my laptop and within seconds my pendrive got detected the speed is good according to the price bracket and it has been 4 years and I find no problems in the pendrive, it is easy to use just plug and use it comes along with some useful apps from sandisk like sandisk valut which keeps pendrive data safe and the sandisk services is great I got 5 years of warranty so no problems and in future I will buy sandisk for my storage solutions
