    I returned the Sandisk flash drive USB 2.0 and got this instead because my first one broke within the first 24 hrs upon receiving it. I bought it online but brought back to customer service, because it broke, at one of the stores and they were so helpful as well as gave me an exchange right there to this 3.0 Flash USB Drive. I had to pay a few extra bucks for this but it was worth it...I love this Flash 3.0 USB Drive!!!
