      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 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!

      Excellent, Very Fast

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.

      Works as advertised.

      Unfortunately, folks don't always fully understand the numbers they read. First, this adapter works fine on a MacBook Air running Lion. Plug and play. Sec Unfortunately, folks don't always fully understand the numbers they read. First, this adapter works fine on a MacBook Air running Lion. Plug and play. Second, this isn't a 1000Mbps Ethernet adapter, and has never been advertised as one. The USB bus wouldn't support that kind of transfer speed. The adapter tops out at 100Mbps because that's the only common-denominator speed between Ethernet and USB; there's no such thing as "480Mbps Ethernet," so you can't "fully utilize" the USB bus potential. Ethernet is either 10, 100, or 1000 for most desktop/laptop computers; 100 is the fastest that USB can handle. If you purchase this (or did so already) expecting faster speeds, then you had bad expectations. So this works as advertised.

The cable is not frayed, I did not use it the whole 3 years, but plugged it in recently, perhaps a year ago. Although cables have a 1 year waranty, most cables of any sort do not fail after 1-3 years. I was also disappointed to learn that the speed is restricted to 100mbs.

      Works well until it breaks

      I have used this product for less than 6 months and it doesn't work anymore. The wires got frayed at the base of the cord and just doesn't work. Really don't kn I have used this product for less than 6 months and it doesn't work anymore. The wires got frayed at the base of the cord and just doesn't work. Really don't know why this happens to all apple cables for as much money we pour into them.
