It just works, like all Apple products!
Purchased this for my MacBook Air and it works flawlessly! I use wifi 90% of the time, but for those rare occasions that wired is the only way to go, it's nice to know that I just jack right in and get to work. I work in IT so having access to both wired and wireless connections is a MUST for my line of work!
By the way, a quick word about the the adapter only being 10/100 vs Gigabit capable. This is not due to Apple being "cheap" or controlling, but rather has to due with the inherent limitation of the USB connection itself. See, by definition, USB 2.0 has a theoretical maximum bandwidth of 480 Mbps. This means that USB 2.0 - at a maximum - is capable of less than half of the maximum Gigabit speed (1,000 Mbps). So even if Apple would've included this feature in the device itself, the bus the USB connects to internally would prevent it from ever reaching anything near that speed, plus, the device probably would've cost about 300% more since most Gigabit-enabled products usually cost approx. that much more for that capability.
My only (slight) complaint is the lack of status/link lights on the device. Again, from an IT standpoint, that feature is a welcome addition, however, being an Apple product, Apple does not include these lights on any of their products (MacBooks, Apple TV, Mac Pros, etc.) so I didn't expect them to include it...just a personal preference is all! …

Now Only Works With MacBook Air
This little gem used to be the device of choice for adding a second Ethernet interface to a Mac Mini Server and I'd been using one that way for about a year. After doing a software update to 10.6.6 it stopped working. Forewarned is forearmed – it appears that Apple is finally enforcing the MacBook Air system requirement. Bummer. Two stars for downgraded functionality. …

Excellent, Very Fast
I have good wireless at home and on campus, but thought I'd get this as a just-in-case accessory. Turned off Airport and connected the ethernet cable and the speed increase over our wireless was significant. Well worth the money and there when I need it. …

Did not work with my 11" MacBook Air 2012
Bought it to connect my 11" MacBook Air to the web using cable (faster). Did not work on any of its USB3 ports. Looked on the web and many said it doesn't, I had to use the Thinderbolt adapter, which is faster also, up to gigabit Ethernet.
Returned it. …

Apparently No Longer Supported
After a recent update to 10.8.3 build 12D78, this device no longer works on my MBA 13" Checked with local Genius Bar, and chat su pport to no avail. Great as long as you don't update, worthless after you do. A patch from Apple would take it back to 5stars. …

Solved Streaming Problem
Excellent product. It worked immediately the first time that I tried it. No problems at all, and no set-up required other than plu gging it in to my MacBook Air. It boosted my connection speed enough, compared to wifi, to overcome a problem that I was having streaming high-res content from an unusually demanding source. Highly recommended for any MacBook Air user who occasionally needs Ethernet. …

Sometimes you actually do need 2 working Ethernet ports. I can think of many applications for 2 port s.
Many network firewalls use one port for incoming traffic and the second for outgoing traffic.
With that said the adapter does work on a MacBook Pro, but this may change in future updates. …

Will this adapter work better than the wifi connection eliminating or minimizing video streaming freezes?

Yes, it is always better to use a hardwired connection for video streaming. However, there are many possible reasons for a video stream to freeze/buffer so this may not solve your problem. …
