Seems extremely cheap for a true Thunderbolt 3 dock. I purchased one for my MacBook Pro (as I'm looking for a true one-cable setup for work) - there's not a tonne of info online, but how wrong can you go. Only big omission is more USB-A ports, but this can resolved with a cheap adapter connected to one of the USB-C ports.
It does dual 4K 60Hz outputs (one over DisplayPort, one over USB-C), which is what I'm looking for.
Good price for a TB3 dock! I would recommend that anyone who wants to dock their laptop over USB-C spring for a real TB3 dock rather than a shitty DisplayLink one.
