Review on Laptop Ethernet Dock: LENTION 3 USB Ports Hub with RJ45 LAN Adapter for MacBook Air/Pro, Chromebook, Windows - Expand Network Connectivity! by Douglas First

One of the ports stopped working immediately. I explained this to the company when they emailed me to see how happy I was with the product and they wanted pictures, computer models, equipment used etc. WTF. I buy another one from another company and then return this one. I'm not a computer genius. The port stopped working. Stay close to your product. Either replace him or say you won't and get over it. Don't make me call and do something if I don't know about computers or devices. Don't waste your time shopping because if something goes wrong they will guide you through the rigmeral to get a new one.
