USB Duo

This is not the fastest USB I have ever used but it will plug straight into my phone without an OTG cable.

Will Connect to my computer and phone with no cable required

None

Beautiful drive

I haven't tried the USB2GO functionality - I bought this primarily as a cheap big USB drive. As a big USB drive, it works beautifully ;) It's a joy seeing files transfer as fast as they do. The black sleeve covers the micro-USB connector, but the full USB connector is left uncovered.
