    I was concern if I could manage this product. See I don’t even have the correct verbiage. I’m almost 70 years old . However this disk was so easy. I didn’t have to do anything but insert and it did the work for.

    Best Flash Drive Yet!

    this is the best flash drive I've purchased, the storage space for the value is great! I only down side is having to carry my adaptor around with it so I can connect it to my Apple devices, but its amazing other then that. I can transfer between home and work so easily I LOVE it, with home being MAC and work being PC. (Typical flash drive is formatted to either Mac or PC but not both so you'll try to use it on one device and it won't allow you to use it)
