      Very fast but.... (rMBP)

      It is a very fast adapter, bought it for my rMBP to use at uni. the issue is that it falls out VERY easily, which is somewhat of an issue for me. when working a It is a very fast adapter, bought it for my rMBP to use at uni. the issue is that it falls out VERY easily, which is somewhat of an issue for me. when working at a desk its fine, but at other times it gets knocked even just a little and it disconnects and takes a while to reconnect. This is annoying!

      works fine but it's a shame you need one

      The adapter works fine connected to my macbook pro with retina display, and my macbook air, in that it allows you to plug your ethernet cable into the computer. The adapter works fine connected to my macbook pro with retina display, and my macbook air, in that it allows you to plug your ethernet cable into the computer. It's a shame however that the thunderbolt plug and socket are not nearly as sturdy as ethernet, and come out far too easily, which is very frustrating. But the real issue is that the computer doesn't come with an ethernet port. I can understand in the case of the macbook air that they are all about thinness, and ethernet is fractionally thicker than thunderbolt. But a MacBook Pro should not be without ethernet. Professionals using these machines rely on ethernet all the time for transferring large amounts of data. The photography, film and music industries all use ethernet to transfer data to and from computers and servers. And carrying around a flimsy adapter that falls out of it's socket with a gentle nudge just isn't a viable option. But until Apple changes their "pro" design, I guess we're stuck with these silly, flimsy and overpriced things.

      Periodically stops working physical connection loose

      This dongle stuff is not reliable over time. On my 2015 MBP, the lightning connector for this adapter is loose in both ports. I will be running web meetings This dongle stuff is not reliable over time. On my 2015 MBP, the lightning connector for this adapter is loose in both ports. I will be running web meetings and if my laptop shifts or I bump the cable, the network disconnects, killing my meeting. It's really frustrating to have spent $2,000, then $30 for this connector and have unreliable Internet. I don't know if the flaw is with the adapter or laptop ports, or both. Just ridiculous to have this problem. I was better off with tech in the 1990s, then I plugged in network cable and it never failed.

      Product does not work as described

      I have two of these adapters. After updating my MacBook Pro to Sierra, I can no longer get either adapter to connect to my GigE LAN. In System Preferences > Net I have two of these adapters. After updating my MacBook Pro to Sierra, I can no longer get either adapter to connect to my GigE LAN. In System Preferences > Network, the Thunderbolt-Ethernet service indicates that a cable is unplugged. However, in About this Mac, the adapter shows up as plugged in. I've tested all connections, applied every update and tried every fix out there. Doesn't matter, no connection to GigE LAN. Before this failure, I could transfer large files from my MBPr to my LAN at GigE speeds. Now, the MBPr can only access my LAN at WiFi speeds - less than 10% as fast. PITA. This is a known issue (do a search) affecting many. Apple hasn't fixed it. Apple killed functionality of this adapter. Don't buy it. It will not work for you.

      Poor Design

The wifi signal in my facilities aren't ve Understandably, it does function properly. However with my circumstances, I'm always moving around with my Macbook. The wifi signal in my facilities aren't very strong, so I am to resort to this method. With that said, the adaptor itself always loses connection very easily when my MacBook moves but an inch. It would have been a very smart idea for Apple to have an integrated clip on the thunderbolt end of the adaptor, and on the MacBook itself 'inserts' for the clip to latch itself. When wireless internet fails, this minor flaw is clearly an annoyance, especially when this product is overlooked due to convenience and short term design.

      Truly awful, do not buy.

      I was having latency issues while playing online games through the wi-fi connection (both 5.0 and 2.4 ghz), so I decided to upgrade to a more stable LAN connect I was having latency issues while playing online games through the wi-fi connection (both 5.0 and 2.4 ghz), so I decided to upgrade to a more stable LAN connection. Naturally, since Apple seems to hate standard I/O, I had to buy an adapter, and I unfortunately chose this one. I went from a latency ranging between 70ms - 160ms, to a range of 40ms - 12380ms (12 second delay). This is atrocious as no other LAN connected computer on our network has these issues, they are specific to the Ethernet adapter. This is a horrible piece of technology and I am demanding a refund. Do not buy. These should be incinerated instead of sold.
