I've used many different adapters and this one seems to be a nice one for portable use with my MacBook Pro / Mobile Phone
It's cool it has an HDMI adapter and dual ports for USB-A. I still have dongles that don't have USB-C equivalents (thanks Logitech! :P).
The only downside is that there's no USB-C power pass through. Shouldn't be an issue since you can connect everything up with just this one USB-C adapter so there's at least an extra one for your power.
Haven't done anything to test whether it's truly Thunderbolt and dual USB-A 3.0. Maybe I'll try to back up on my external hard drive. Will report back if I have any problems there.
