Set Up Three 4K Monitors with Ease

Great dock, heavy
Works well, but it's a bit bulky and heavy for travel. Fine for desk use. The 100W charging is excellent.

Reliable and versatile
I've been using this dock for a few months now. It's stable, no disconnects. The triple monitor support is great. The only minor gripe is that the USB ports are all on the back, but that's minor.
