Granted, this product is nice but I'd advise anyone to think twice about their needs before purchasing. I realized after I got it that a MacBook Air can only take one thunderbolt adapter. And the reason I usually need an adapter is because I'm at a conference podium where the wifi isn't usable. You can't use both this and a display port adapter at the same time so I had to also get a USB adapter.

This adapter is super fast so I plan to keep it for any time I need to do big transfers. But definitely consider your needs a bit more carefully than I did.

I use this cable with my 15" MacBook Pro with Retina display, which has two Thunderbolt ports. I am in a University setting where I get pervasive wireless coverage, but I prefer the hard-wired connection's speed, the constant connectivity, and the ability to access networked drives. It is expensive but I very happy with its performance.

Things I really like about this connector:
1. It makes a fast connection. The speed of the data transfer through the connector is a bit hard to gauge in a 'normal' setting since I get almost 100 Mbps on my connection (thus I am not sure I would notice if the connection was slowed some due to the connector).
2. The connector is easy to use and mostly unobtrusive (see below). I am able to plug it in and nearly instantaneously have an internet connection. In addition, my internet connection is up and running as soon as I wake my computer up, which is not always the case with my wireless connection. I am particularly pleased with this re-connection speed.

I do wish they would have used a slightly more flexible cable though. The cable that connects the computer side (the Thunderbolt connection) and the internet connection (the ethernet connection) side is fairly stiff and it unfortunately does not bend out of the way of other cables very easily. It does not interfere with the power cord at all (that connector is quite small), but if I plug in another thunderbolt connector in the real estate on the left side of my desk gets crowded.

A couple other things I have noticed, but that have not yet caused me any problems. The ethernet connection side gets warm during use, though not hot. Also, as other reviewers have pointed out, there is some wiggle room in my Thunderbolt port.

I have a MacBook Air that I needed to connect to a wired network *and* use my Thunderbolt RAID. I thought I was out of luck. Turns out you can plug this adaptor into the end of your Thunderbolt daisy chain so you get both Ethernet and Thunderbolt connection at the same time! It doesn't have to be directly connected to your Mac. Just make sure your Thunderbolt drive has two plugs so you can daisy chain it.

Gets the job done if you need to do transfers of large files, as the gigabit speeds are much better than you can get over even the fastest wifi.

So far so good. I rather think that this should be part of the macbook instead of having to carry so many adapters. Thin and slim. You win some, you lose some.

It works great with my Macbook Air. There is no ethernet port on my Macbook Air and I had to find a way to use it. I didn't choose USB to ethernet adapter since there are only two USB ports on the computer and I sometimes use two USB devises. The thunderbolt to ethernet adapter works great. No complains.

I am using the adapter on my 2011 Mac Mini as an additional network interface. I have a Synology 5 bay DS1511 NAS with two network interfaces and I wanted to use the TB ethernet adapter to connect as a private channel to the second NAS net interface. This all works as expected. I have an SSD as my main drive in the Mac Mini and have a 5 disk raid 5 on the NAS. I set the MTU for the NAS and the TB adapter at 9000. On transfer tests for large files I am seeing 118 MB/s peak / 110 MB/s average download speeds and 112 MB/s peak / 100 MB/s average upload speeds. This in the range of what I would expect on a 1Gbps ethernet.

I also got the adapter working booting into Windows 7 x64 with the Broadcom drivers. Similar speeds.

Basically everything works as expected (5 stars), however (-1 star) ...

My Mac Mini no longer stays in sleep mode. This is a known problem with this adapter - Apple's solution - don't use the adapter on the Mac Mini - use the built in ethernet port. I am not happy about this and hope Apple fixes this with software in the future. I really like having two ethernet ports but don't think I can go without the ability to put my Mac to sleep.

I certainly can't complain about this adapter: it's well built, it's got the Apple aesthetic, and I get comparable speed test results to a computer with an ethernet port directly on it. But, I'd rather buy a USB 3.0 to gigabit ethernet adapter for a comparable or slightly lower price, given that it will work on a wider range of computers that might not have Apple's proprietary Thunderbolt port. If you've got a Mac with Thunderbolt and USB 2 (no USB 3), then this is clearly the better decision because USB 2 is limited to 480mbps. But if you've got USB 3, why not just go with that? I will say, though, I have yet to find a USB 3 to gigabit ethernet adapter with quite as good of build quality as this Thunderbolt one.
