I bought my Xebec for my MacBook Air 2017 (without doing the proper research). Due to limited USB ports, it would not work out of the box without the proper additional adapters and a resolution adjustment in the Display Preferences. The personalized customer support I received is the best I have experienced from ANY company. I am 58 years old, retired law enforcement and far from a tech geek. These folks (Megan and Leo) were patient and persistent from the start. They assured me that they would get me to the solution, and they did, without once making me feel like a dummy. I love the product as well. I do some freelance writing and research and this will make it so much easier to do my site references while in travel and at my cabin in Maine. Great innovation, great product and awesome people.
