Works with Mac
This is a really great docking station. It supports windows as well as Mac. For windows, it is an easy plug-in play however for Mac, the user will need to install drivers from display link website. Once the drivers are installed, the product works flawlessly.

A game changer devide
As an accountant, I work with multiple excel documents, and I used multiple displays connected to laptop via HDMI and USB-c ports until very recently our company replaced HP laptops with Microsoft Surface laptops. Unlike my previous HP laptop, new surface laptop came with one usb-c port and one usb-a port, which was quite frustrating as I could connect only one external displays. Microsoft offers docking stations for surface laptops with the price starting at $200 which is quite expensive for my budget. After several days of searching for the right device, I decided to try Dell docking station, and I wasn't disappointed. It works perfectly for me, I can connect 3 external displays (1 in laptop's usb-c port, and 2 displays in the docking station, 1 port remains available) which is crucial for my work. The docking station also comes with multiple usb-a ports and 3.5mm audio port which is very convenient. As a warning, the device is not plug & play and not identified by windows on my laptop, I had to download a driver from Dell website. Also I am not sure if this docking station can be used for gaming, sometimes there are lagging issues with the image. Otherwise, I am very happy with this docking station.

Happy with this Dock Station
I spent some time in research prior buiying this product, really liked the idea of having a wireless charger instead of a black box on my table. Reading the negative reviews - I was looking into 3 things: 1. Receiving used products instead of new ones; 2. Receiving products with already activated support service; 3. Ticking noise during charge; All 3 were not true in my case, all good and working as intended. Even the charger works without connect to the laptop (I am almost sure). Only thing to be advised: This Dock Station provides power supply up to 90W. Modern high performance laptops may tekae more. In my case - laptop takes 130W and while charging with dock station only I have received "Battery Slow Charging" alert message. The solution is to power up laptop with native charger, but use the dock station to connect all necessary devices. Fun fact, my second laptop has identical specs, with CPU of gen 10 instead of 11, and it takes 65W, works flawlessly with this dock. I guess - thats marketing for you.

Some drawbacks, but otherwise a very nice piece of desktop computing awesomeness.
Well, I have been using one of these docks for almost a year now, and I have been extremely impressed. The picture quality is great, and the functionality is very reliable. I do, however, have two complaints. Firstly, the setup is not as simple as it should be. There is firmware available on the Dell website, as well as on the DisplayLink website, but no native software application for managing the displays once installed. You are forced to use the Windows display management software, which is absolutely not user friendly, especially if you are running triple monitors or more. It takes some time to get everything set up and working properly, but once you get it done, you should not have any further issues. Secondly, this dock has a DisplayPort output. If, however, you own or intend to purchase monitors, like my three Dell U2414H flat panels, with MST (Multi-Stream Transport) capability (aka Daisy Chaining) you will be disappointed to learn that this dock does NOT support MST. Rather than connecting multiple monitors to one display output, you have to run a separate video cable for every single monitor. What's worse, the dock only has one DisplayPort output, the other two outputs are HDMI, so if your monitors came with DisplayPort cables like mine did, you will have to buy additional HDMI cables as well... None of these issues is a deal breaker, and now that I am set up, I am EXTREMELY happy with the end result, but just a little bit of info I wish I had known prior to making my purchases.

Lasts a long time - good quality.
My last Dell docking station lasted a LONG time, but finally had enough forcing me to get another. What did I buy? I’d always buy this again because of its reliability and quality.

Es un producto muy útil. Le conecté dos monitores Ultra wide, mis audífonos, un dispositivo bluetooth, cable ethernet y hasta ahora sin problemas. Lo uso con una laptop acer y no he tenido problemas de compatibilidad.

Tengo una lenovo t14, trabajo desde casa con 2 monitores externos. El dock es compacto y no se sobrecalienta demasiado, casi nada. Carga perfectamente la lap y ahora ya uso solo un unico cable (del dock a la lap). En el dock tengo conectado dos monitores (1con hdmi,1 con displayport), el cable ethernet y los ocasionales usb A y aún me quedan libres otros 2 o 3 usb A y un usb c. Soporta perfectamente daisy chain usando si usas la salida display port (tuve que comprar cables nuevos display port). El cargador inalambrico es un plus pero no lo uso tanto porque cargo mucho más rápido con cable. Excelente calidad de construccion. Muy muy recomendado. (Edit: además funciona como almohada para tu gatito)

Super petite station d'accueil répondant à presque tous les besoins d'un utilisateur en télétravail ou d'un utilisateur de PC portable (+ écran). Sa compatibilité élevé reste un vrai plus du fait de son fonctionnement par USB 3. Attention toutefois, il est nécessaire d'installer un logiciel Dell pour gérer les écrans externes ce qui peut être limitant dans le cas d'ordinateur de travail (appartement à une entreprise). Si c'est le cas, demander avant de l'acheter au service informatique si il est possible d'installer le logiciel en question (voir sur le site de Dell). Pas de recharge par la station d'accueil, pas de thunderbolt.

Does everything it says. Adds versatility and flexibility to demands AND charges my phone on top of the additional ports. Looks minimalist and doesn’t clutter the desk space. Occasionally some light buzzing noises come through. But has not affected functionality.
