The package came within 3 days and this is what it looks like:
The adapter was plugged into a USB 2.0 port on my Windows 8.1 laptop and it was automatically installed and ready to use in under a minute. It is slightly stronger than my internal Wi-Fi adapter, at the same moment my internal card recognized 31 networks while the TP-LINK recognized 34. I tested it for several hours streaming 1080p videos on youtube, opening 12 tabs at once on chrome and multitasking, and streaming music on iTunes radio and it held up very well. The connection did not drop once and so far it has been great.
