    • Quality dock
Working well so far. Have not connected two monitors yet. Seems to be solid.

    • Arrived DOA. Late Gen.
Bought used through Amazon. It arrived DOA. Power did not work. LLM I used to troubleshoot think they shipped the wrong adapter. Either way, I am really annoyed I have to return this. Also this is an older gen dock.

Just plug in and go. All the outlet video connections are 4K capable and provide a crisp clear picture.

    • Great port replicator for X1 Yoga gen 4
Great port replicator with all the ports you’ll need. Single complaint is that it doesn’t have mounting holes for wall mount. Edit 9/2023 I've had this for almost four years now and it is hands down the best dock I've ever used. I run 2 2K monitors and one UWFHD for a total of three monitors. It provides plenty of power, 5 USB-A and one USB-C, two DisplayPorts and two HDMI ports and a 1 Gb ethernet port. If you're going to run multiple high-res monitors, you must have high quality cables. The free one that came with your monitor probably won't cut it. I initially had issues with monitors cutting out until I replaced the cheap cables and now it runs perfect every time. ... show more

    • Original Lenovo docking station
Per specification, this docking station fills the expectation perfectly. I've been using it for years and enjoys it very much.

    • Not compatible if not Lenovo
Not compatible with all laptops or pcs. If you've got a Lenovo, which I do for work. It's very reliable. But I bought one for an HP Laptop thinking it would work. No. It lacked some functionality. Get a dock from your laptop's company to just avoid a lot of problems.

    • Not as advertised.
Review Image by Brian Mountin
This product is clearly not new and is NOT advertised as refurbished. We had to do a return on the first one because the aftermarket lightening cable could not support the data transfer required, only charging. So no video or even wireless keyboard/mouse dongle capability. The 2nd unit arrived with the same non-functioning aftermarket cable. Do not buy this from this vendor buy a refurbished one for $100 less or find one that is actually new in the box from Lenovo. ... show more
