    Loads files fast. I use it for playing music in my 2016 Chevy radio. Recalls files very quickly. Got a great price on it too. Wish the case had a switch for the USB to stay projected out easily.

    Works great and does it what it suppose to do. I did not used the apps that came with it as I never do. I can see the speed difference from other brands USB I own. No heat issue for me.
