The USB 3.0 capabilities are also appreciated, along with its comfortable size.

    I use this every single day. My only complaint is that the plastic hole for the keychain broke quickly. If you are going to use it with your keys, you might look for one that has a metal ring otherwise this was a great buy and works well.
