I was looking for a small managed switch, so I can force port modes/speeds when needed, do port mirroring to debug issues on other devices, etc, so I got this since it was a good deal at $63.99 back in 2012 when I purchased it.
This switch is very well constructed, with full metal housing, and doesn't even get warm during operation. The wall wart power supply is small, and doesn't get warm either, which is great.
The switch works right out of the box, however to manage it you need to have your computer in the 10.0.0.0/8 subnet at least momentarily, to talk the the switch at its factory default 10.90.90.90 address and make any changes. (Tip for linux users: something like "ifconfig eth0:2 10.90.90.2 netmask 255.0.0.0" immediately allows your computer to talk to the switch without interrupting your regular connectivity at all.)
The switch readily recognizes FE vs gigabit-ethernet devices plugged into it, and depending on the speed of the device, either the amber or the green LED on the switch port lights up respectively, giving you instant visual confirmation of what the speed is.
The web interface to manage the switch is nice, also reporting speed/duplex for each port, cable faults, and allows you to setup port-based or 802.1q VLAN's, IGMP snooping to reduce broadcast traffic, port mirroring, SNMP traps, report of learned mac addresses, loop detection, QoS, port trunking (static link aggregation only, not LACP), storm & bandwidth control, backup & restore of configuration, etc. There is no CLI interface though, only plain http (no https either).
I tried the port mirroring and it worked great; I was able to tcpdump packets on my computer being exchanged by 2 other devices on my home network (you can mirror any port to any other port on the switch, however multiple ones at the same time is not possible).
One thing the switch USED to lack, is support for jumbo frames, which might have been an issue for some, however, unless ALL your devices on the same LAN (including your router) can support jumbo frames, you cannot use them anyway.
UPDATE: Jumbo frames (9216 bytes) are now supported, just upgrade the firmware to 1.10.007 or later.
Another issue I had noticed, is some small number of RX errors reported on the switch port where my computer was plugged in (even though everything was working fine otherwise). I tried changing speed and duplex settings to no avail. Finally I noticed that 802.1q was enabled (all ports were in the same VLAN) and when I disabled it, the RX errors stopped.
UPDATE: Firmware 1.10.011 resolves this issue!
The user guide says 802.1q is by default disabled, but I found that the factory default settings is in fact enabled.
The switch is small, sturdy, has nice features for the price, works well and stays cool, so I'm pleased with it and would buy it again!
UPDATE Jan 2018: This switch has been flawlessly handling my traffic for over 5 years now! I'm using it along with an Ubiquiti EdgeRouter Lite (awesome 3 port gigabit router) and couldn't be happier with the setup!
UPDATE Sep 2021: The switch still running great after 9 years! My hardware version is A1 and I'm on latest firmware 1.10.039. My uptime currently is 564 days, ie there hasn't been any reboot in over 1.5 years (basically since I last updated the firmware) !
