I don't have any more to say than that it works as designed. I needed to get more Thuderbolt ports than the 4 on my MBP, and this was the only device I found that gives you one extra USB-C port after taking up one on the MacBook Pro to connect it to. It seems wells made, simple, elegant design. The color is a little darker than my silver MBP, maybe closer to space grey. Attractive and compact nonetheless. I will not hesitate to purchase another one or more if I need more USB-C port.
