I have this in the frame bought my work from home. I needed a dock compatible with a 2018 MacBook Air that only has USB-C ports and an Ethernet port, and this one fits. I place my MacBook on top of the port and haven't had any overheating issues, plus I love the angle it offers. I only have two problems: 1) the ethernet cable doesn't "sit" in the port so sometimes it comes out, and 2) with the port, my 45w adapter doesn't have enough power to power the port power and charge my MacBook, so I unplug the power and plug it directly into your MacBook to charge when needed.
