Although having a port on your machine is more ideal, this nifty gadget does exactly as it’s meant for. It’s very portable with my other adapters and such that I take on the go. I feel an ethernet plug is one of those essential ports that should be part of the machine, but because they don’t build them into the machines anymore, this is the next best thing. I find that this works fantastic to use for an ethernet connection using my Thunderbolt port of my MB Pro. I currently have a MacBook Pro Late 2013 Retina model. It has never failed me yet. Not sure about the other reviewer problems mentioned, but my use has been minimal, and has been for general use of modem/router & printer setups… or basically when direct connection is required for an initial setup and/or bluetooth setup, etc. I can connect to my device via ethernet just fine without getting errors or other problems. It was a great investment for me!
