I like this hub more than other hubs I've tried that connect directly to a MacBook. I have a feeling those that connect directly are more likely to break if you accidentally strain them while moving the MacBook. With a wired hub, I worry less about bumping into things. I've tested this with a 4K monitor and it works fine at 30Hz (note that it only works with a 4K monitor at 30Hz or two 1080p monitors). Power pass-through works, as does connecting directly to a MacBook via the power adapter.
