As with most Linksys products, this product is a great buy. The easy-to-use web-based management system, convenient and stylish design, great performance, excellent security and good driver/bios update support, and Linksys's great customer service make this a good buy for users of any level.
I've personally bought and installed 15 of these devices (some were the 8-port model, but the same product overall) for some of my clients who need VPN and firewall support for their private networks over their broadband connection. Remote management support also makes administering these a snap.
