    This thing is awesome

    Love this product. Running dual monitors with my M1 Macbook Pro and it works like a charm. Also have my microphone and camera attached. Sits nicely on my desk and I'm so glad I purchased this.

    Dual Monitors on M1 MacBook Air For The WIN!!!

    Not much to say here other than the fact that this adapter does what the computer itself can't do: support dual monitors on an M1 MacBook Air. Installation of the companion software was simple and straightforward. Words exactly as expected. I've already bought 3 more for users who were needing a solution like this.

    A great converter device for the M1 chip Apple laptops.

    Very good, well built device. I would have liked an USB3 option.

    Great product, exactly what I needed

    Something like this is so hard to find. I don’t know why. It seems like a lot of people need something like this. The software needed to run both monitors was easy to use. The additional ports are very helpful. The only criticism I have is that I wish the cord was a bit longer or had a detachable option that could use an extended cable. I’m using it on my MacMini and it has to stretch a bit far to get to the correct port based on my current set up.
