Compact size but huge performance
This thunderbolt hub is just what I needed to add a few mort TB ports to my iMac. This is a great quality unit with a metal enclosure but it's not too heavy and doesn't get too hot. It adds 2 additional ports plus another USB3 port, which is helpful for connecting other older accessories. I like that it has the separate power supply so it can provide PD power if I plug in my iPad or phone to it. It's almost comical that the power brick is twice as big as the hub, that how small it is! Setup was simple plug and play and no issues at all so far— the data is flowing very fast! I've got an external RAID connecting through the hub and not seeing any bottlenecks.Highly recommend this hub for it's performance and portability (kind of, except for the giant power brick), and it's not a bad price.
