second one purchased- works as intended, reasonably priced.
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.

Quick Delivery
Wasn't exactly what I expected, I didn't pay close enough attention to the Adapter end. Thought it was a standard USB plug. Not sure if it works because my laptop doesn't take USB C and it did not work through my connect device. Received on a timely basis.

Not good for long term use
Worked like a charm for 4 months. Now as I'm attempting to work on my dual monitors that are connected to my laptop, the connection "falls" off multiple times a day. I've tested the individual monitors (which are only a few months old as well) and neither of them have a problem when connected directly to my computer. It's the one (or both) when I had both of them connected to this splitter, that continuously fails now. I'm out of the return window now so I'm upset that I spent money on something not reliable, that is slowing my work day down and now I have to buy another product. I DO NOT RECOMMEND THIS PRODUCT!!!

Did not work on my 2 yr old HP but worked on Lenovo
I got this so I could use my HP laptop with two external screens. However, my computer did not recognize the connection at all. It's not a particularly old PC, I got it less than 2 years ago and the specs are still pretty current. I just got a new Lenovo laptop as well and the extender worked perfectly. I was able to set up two external screens (along with an extrnal keay baord and mouse as a desktop work station and keep my laptop closed. ) It did have an option for using the laptop for the 3rd screen but I don't need that.

Works great!!
So I not long ago I got some monitors and they came with 2 HDMI (one for each monitor) and I couldn’t get them both to connect to my laptop. I ended up purchasing this and it works great!!! I can do use both monitors and my laptop at the same time. The are all independent monitors so it’s not mirrored. This is very helpful when I’m having to work on essays and need to do research. It was extremely easy to set up. Have absolutely no issues. It’s great!

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...

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 👏
