USB C Docking Station Dual Monitor, 9 in 1 Triple Display Docking Station to Dual HDMI Adapter Displayport SD TF Card Reader 2USB 2.0, 1 USB 3.0, 100W PD for USB C Thunderbolt 3/4 Laptops

I wanted to attach two external monitors to my notebook for home office reasons. I only wanted to use two external monitors, not my notebook screen. One external screen as main screen, second as "extended" screen. Works perfectly.My notebook has one HDMI slot, where I connected my first external monitor so far. My second external monitor has also HDMI. Bought this little device advertised here, plugged the second HDMI cable in the little device and then connected the devise to my notebook in the USB C slot. It immediately recognized the second screen, as extended display, resolution was also great. Nothing I had to do, I was surprised.Next I unplugged also my first monitor with HDMI from my notebook, and also plugged into the second HDMI slot of the little device. Connected the little device with its USB C slot to my notebook. Same result, works perfectly.Next I connected my printer and external webcam also to the device. All works perfectly. I continue to use my notebooks keypad (I prefer that keyboard, simply put the notebooks screen quite flat, underneath the external monitors, so it does not disturb the view). So I have not tried attaching an external keypad or mouse to the device. But given that all other devices worked, I am sure that would also work.Result - I have USB C cable to connect to my notebook, and everything works and is set up. I have also disconnected and connected again. Everything works. I intended to buy a 200 USD docking station from Lenovo, which was not available, so I said lets try this one. I certainly do not regret my choice. It does not have a power supply, so I do need to connect my notebook to power, so 2 cables instead of one, if I had bought the Lenovo version. Also I was worried about the notebook getting too hot. This is not an issue (I have AC my room, so my room is not extremely hot).Only thing I do not like is that the USB C cable is a bit short, so all the other cables going to the little device are a little too close. And that cable cannot be replaced (it it attached fix to the little device). I assume I could buy an extension cable, but for the moment I do not really care.So it worked perfectly for me, the device is small - and so much cheaper than these Lenovo solutions. I cannot guarantee it works for everyone. But for me, it was beyond expectations.

I bought the “used, like new” - because it had same day delivery. I’m currently a student in a design course approaching the final days and realized I needed another monitor, because the existing one I had (displayed vertically now) wasn’t showing the colors correctly, usually they looked too hot, or neon, despite adjusting the settings. So I purchased an overnight monitor that I intended to connect to my 13” laptop with an HDMI splitter only to find that my display wasn’t being extended to the third monitor, and still I could only use just one. This item not only arrived the same day, but was truly like new (except the packaging a little bent) and came with an Amazon seal of inspection to confirm its condition. The setup was easy and I was so glad that as soon as I connected it to my USB-C and then plugged in my laptop charger that my laptop was *still* charging. My wireless mouse has no issues, and even the cherry on top was that all monitors were able to extend. Really glad I made this purchase, because it’s helped me immensely to get work done more quickly and higher quality now that I can truly see the designs in both Landscape and portrait mode.

I must've searched for hours & read dozens of reviews, mostly products in excess of $200. I just needed 2 external monitors for a MBA M1 for home recording studio. I couldn't understand how these things could range from $30 - $300. Normally I follow the, "you get what you pay for" rule but figured let's give this a try. Worst case scenario I'll return it.First off, these things aren't plug n play initially. You have to install software that essentially tricks your computer into accepting multiple monitors but it's a 1 & done deal. TBH, I didn't have high hopes but to my delight it worked!

To be clear, this is a review of my initial impressions of this device. I'm aware that some other people have had mixed experiences in terms of reliability and q/a with this. I intend to provide a longer term update later.First things first, I am using this with a Microsoft Surface Book 2 which is explicitly on the compatibility list. The SB2 USB-C port does indeed serve video like a champ. It should be noted that the reason I chose this dock in particular was that it had a DisplayPort interface (most newer monitors have this as an option... most of these class of docks have HDMI, but that interface is primarily aimed at TVs. Some have DVI but that's a relatively old standard, and VGA is even older.Regardless, it worked right away, detecting the Dell U3014 monitor immediately as a generic PnP monitor, and served video at an appropriate res and refresh rate.The additional USB 2/3 type=A ports work fine (not a big surprise.) There's no sign of disconnections or other instability other have described in my unit (in my admittedly brief experience.)One notable finding is that the power delivery on the USB-C port is bi-directional (so, not only can you use a USB-C device which draws power, but you, alternatively. can plug a USB-C charging cable into the "outbound" USB-C port --provided your laptop/tablet has a USB-C PD port and can be charged this way.) I'm not sure on the power limits, but I wasn't necessarily expecting much more than getting an image, so a minor plus, I suppose...Anyway, no downsides I can see thus far. Port selection isn't PERFECT, but certainly acceptable, and the inclusion of DisplayPort, at this price is a winner if this lasts.
