It’s been a mixed bag with this hub. My laptop would not recognize an external monitor through the hub’s HDMI port and had to plug the cable directly into the port on my laptop. Currently I have the following attached to the hub: a power cable for my external monitor, a cable for an external HDD that I use for backups, a printer cable, and an Ethernet cable. I friend suggested that I might have too much running through the hub and that I try disconnecting the Ethernet cable and plugging in the HDMI cable. I did but the monitor was still not recognized, so I went back to my original setup. Occasionally I loose the Ethernet connection and have to push the connector into the port. I never had that problem with this Ethernet cable when it was plugged into my desktop, so it seems to be a problem with the Ethernet port on this hub. I haven’t tried the other ports on the hub, so I don’t know if they work. I wonder if I have a defective unit or if this is a more widespread problem. I only turn on the external HHD when I do backups. With the Ethernet cable attached and 2 things powered on, the hub is noticeably warm to the touch. I wonder how hot the hub would get if I were also using the USB C and HDMI ports. In all, I’m not impressed with this hub. Update: Acer Customer Service contacted me. I didn't ask for a refund, but they made one anyway. It really wasn't a problem with the hub but a mismatch with the USB C port on my laptop. Acer's response keeps me as a loyal customer. They went above and beyond my expectations. I am changing my rating to 5 stars due to their excelent customer service.
