The AirPort Extreme is a fast and powerful dual band router with great range. I am able to get very good signal one floor above and one floor below the device. Its size is compact, with the antennae included in the form factor.
This is the current version of the Apple airport base station. It is refurbished (B stock). The base station itself looks like new. The power adapter has some cosmetic defects.
The base station has good coverage. Online reviews say the wireless signal is stronger than the previous model. I can say for sure it is much stronger than my airport express. The hard drive sharing is super easy, just plug an Apple-formatted hard drive in the USB port on the back and it's done.
I used to use another brand, but these Apple Extreme routers are easy to set up and easy to expand with other Apple Express routers. Makes it great for a larger house. Much easier than anything else in the market.
The sleek, easy-to-use AirPort Extreme Base Station with simultaneous dual-band support is the perfect wireless access point for home, school or small business. It offers fast, 802.11n Wi-Fi access for Mac computers, PCs and Wi-Fi devices such as iPhone, iPod touch and Apple TV.
