Summary: A bit bulky. It works well but it lifts up the laptop slightly because it is bigger then the slim laptop (Dell Inspiron) that it is used for. Would fit nicer on a thicker laptop. Next time I will buy one that is attached by a short cable that connects with a small USB.
Excerpt: I have three old laptops/netbooks that I now use for downloading cameras simultaneously while on location at multi day events. These devices work perfectly. There were some negative reviews, but I have no issues so far.
Summary: Works well with my Retina Mac Book Pro. I have been using it for about 6 months now and no problems at all. The speed boost compared to WiFi is significant and since I am on a Retina MacBook Pro with no Ethernet connection, this is dramatic to me.
Summary: I bought this adapter to use in one specific area of my work where we aren't allowed to have wifi for security reasons. It was used with a Surface Pro 2 for about 6 months, and seemed to perform flawlessly in that time.
Summary: After reading reviews on other sites, I downloaded and installed the newest drivers before it arrived since the driver disk has old versions. Once it was here, I plugged it in and it was recognized immediately. It works great and frees up the Thunderbolt port on my Macbook Air!
