It does what it's supposed to. I had to jump through a few hoops to get it working on the Google Pixel, but it works and transfers data. It gets very hot but I didn't burn it. This plastic cover is not intended to protect the connector. It's designed to protect your thumb from burns when you take it off. It's very compact for a flash drive (most compact I've seen). The port is long enough that with a Pixel I could even use it with an enclosure (can't say that about all flash drives).
