Pros & Cons
👍 Pros
- Consolidates multiple peripherals into a single USB-C connection for a clean, organized desk setup.
- Three video outputs (2x DisplayPort, 1x HDMI) enable robust multi-monitor configurations.
- Five USB ports (3x USB 3.1, 2x USB 2.0) provide ample connectivity for peripherals.
- Built-in Gigabit Ethernet delivers reliable wired networking without a separate adapter.
- Included 90W power adapter powers the dock and connected devices out of the box.
👎 Cons
- Designed primarily for Lenovo ThinkPad systems — compatibility with other brands is not guaranteed.
- Maximum 4K at 60Hz is limited to a single display; multiple 4K monitors run at the lower 30Hz refresh rate.
- No Thunderbolt support, which limits maximum data throughput compared to Thunderbolt docks.
- The dock itself does not fold or travel compactly, making it more suited to a permanent desk setup.
