    Doesn’t work as a USB-C extended monitor with Mac

    Great Smart Monitor

    Purchased this smart monitor for my MacBook, IPhone and PC. All of these devices mirror (wirelessly connect) perfectly with this monitor. In addition, it acts as a smart TV so I can watch programs on all the popular apps. Picture quality is very good as is connectivity. Monitor was very easy to set up and easy to use. I would recommend it to anyone wanting a smart monitor.

    Overrated. Dumb device.

    The description is misleading. The device is challenging to setup, heavy, and doesn't connect well to MacBooks.

    Too complicated

    Way too complicated to set up and all the extra smart features are kind of a headache to navigate. All I wanted was a good extra monitor for my laptop but this just way too complicated. Am returning although I love the external design.
