Rated 5 out of 5 by from Helpful tool. Very helpful for one connection to get your monitors, ethernet, USB peripherals and power into one plug. Monitors sometimes don't respond at start up and you have to turn them off and on to be recognized. Which it had a couple of more USB C and regular USB ports both in the back and front.

Rated 5 out of 5 by from Makes Life Simple I can come into work, plug in one single cord, and I am ready to go. No more fumbling around with multiple cords. It also makes for a cleaner work surface. My only complaint is that it seems overpriced for what it does.
