Works out of the box.
Brilliant. Connects my laptop to multiple screens.

Does 2 external individual screens, not mirror
Works very well right out of the box. Simple plug and play type stuff. Works with a Lenovo thinkbook I use for work. For anyone wondering it will let you spit out video into 2 separate screens just from the USB C and also the regular HDMI port on my laptop meaning 3 external screens not including the laptop screen. So an ABC setup. If you don't have a HDMI then you'll still have 2 extra external screens, meaning AB. It will also let you do above 60hz but I only have a 75hz so not sure about 144hz. My one complaint would be that it's not the most flexible cable, as in it'll do 90 degrees but not more without fear, and it is a bit short so get some good length HDMI cables to go into it. Very clean design

Used on two monitor setup from laptop
Works really well, allows me to connect a second monitor as the laptop has only one HDMI.

A must have item for multi use screens
Has allowed me to dual monitor my laptop to 2 computer screens with ease the quality of the connection is good although the jewel component is quite bulky so bear in mind if you have really clean cable management you will need to factor in where you’re going to put the actual connection component. I’ve never had any issues with the connection coming away from the screen or laptop sorry the six months I’ve been using the product every day all day. I believe it is a durable product.

Works as described
Works well. I use it to split the screen from my laptop to two additional screens. It splits rather than simply extends.

Supports higher hz!
Originally when buying this i figured i’d be stuck using both my monitors at 1080p at 60hz as this is what the product description says. But to my pleasant suprise this adapter supports 1080p at 144hz! (so long as your device is capable enough) Also have to say the build quality and connectivity is seamless. Really happy and this is now my daily adapter for work, totally worth the money.

Exactly what I needed.
This was absolutely perfect and did exactly what I needed it to do! Doesn't even require its own separate power source. Just works being plugged in to the laptop and the two monitors letting you have 3 screens you can view. Can't recommend it enough. It's not often I'm so pleased with a product, so I had to wrote a review and let others know.

edit 02/2025 C'était la rallonge de 30cm usbc... Je remets 5 étoiles old: Le boîtier débloque complètement depuis 1 mois et quand je vois les commentaires où les écrans crament je n'insiste pas plus...

I needed a replacement for my previous adapter when it stopped working, and was so pleased with the first one I came back and bought another just like it. Turns out the issue wasn't actually the adapter, so the original is still working just fine! Was able to return the new one with no issues, but I did connect it to make sure it worked, just in case I needed to mark broken/defective on the return form. It works beautifully- does exactly what it's supposed to. I don't need- and therefore definitely don't want- a big bulky docking station that can connect every computer made in the last 35 years. Plug and play installation was simple, it takes up NO space, and I was able to easily connect both of my monitors to my laptop for work without having to spend a fortune on a piece of equipment I really don't need. Figuring out my new display settings took longer than connecting the adapter. I've recommended this exact adapter to several of my coworkers who also work from home but don't want to spend a fortune on extra equipment not covered by the office.

Yes I can confirm this works extremely well and it was pretty cheap compared to the other options, did not overheat at all, the connector was strong and the picture quality was as expected with no delay at all. The problem arose when I tried connecting it to the usb a port using a/an converter/adapter but it did not work. I think no stars should be deducted off this product as it was not intended to work with a/an connector/adapter and might also be the connector/adapter's fault, but in all it does not work with a/an connector/adapter, but works well with an usb c output port, the great lads at amazon helped me by accepting this return so kudos to them 👏
