Summary: I have a DIR-825 Router so I wanted this so it kinda matched although one is black and the other white. There isn't anything to dislike, it's a router, I guess if it went wrong quickly then I'd be un-happy.
Summary: Today, the second of our twin units (bought at Amazon in 2009, 2 years 6 months ago) failed. Within 3 weeks of each other. That smacks of planned obsolesence. The units worked fine until - nothing,one yellow light (#5) and the rest blank. Resetting did nothing. I trust d-link and they have good products (we have 6 other of their components here) but this switch is NOT reliable. Sorry D-link.
Summary: Installed this on my network in March 2010, and it has been problem-free. Data transfers between computers connected to this switch average 60 MB/s + speeds. Makes backups a quick and easy task.
Summary: "Just works" doesn't seem like a very high bar for a wired gigabit ethernet switch, but sadly not all of them do. I have 3 of these around my house (as well as the 8-port model) and never a glitch.
