Pros: Inexpensive for 8 ports, but not as cheap as it looks once you add 8 cables.. Quick & easy to set up. I especially like that there are 15-foot cables available. No need to separately buy extender cables to connect to computers that are farther away. I'm not in a rack-mount environment, but it fits nicely under my monitor.

Cons: This does not transmit constant monitor EDID. That's the signal that tells your computer what monitor type you have. Windows 7 (and I assume 8, I haven't gone there yet) contantly polls your monitor to see if you've disconnected it. Why? Who knows. Lots of people turn their monitors off or have KVM's and it should have no effect. Microsoft calls it a "feature". But it's not something you can turn off. If it's a "feature" it;'a a poorly thought-out one. With some display adapters and drivers in Win7 (maybe most, I have one that doesn't), the screen will re-size to the smallest available when the moniotor is not attached for some period of time. And with this KVM, the computer thinks the monitor is detached when you select another port. When you come back, any windows you left open are crammed in the upper left 1/4 of the screen (more or less, depending on monitor resolution). It's even worse in a dual-monitor configuration. I read of a work-around where you disconnect pin 12 of the monitor (where EDID comes in) and configure it as a non plug-n-play monitor. Haven't tried it. It's not a unique problem with Trendnet -- the internet is full of folks complaining since Win7 came out. But ones that don't do this cost more than twice as much, so I put up with it. I have also seen the "dead mouse and keyboard" issue. It typically happens if I power cycle a computer while the KVM has that computer selected. If I switch away before it powers down and back while it's powering up (but early enough in the boot that it detects the monitor correctly), everything seems to be OK. When the problem does happen, you can unplug and re-plug the USB all you want, it'll do no good. It gets detected as an "unknown USB device". Only disconnecting and re-connecting power will fix it. Since having multiple machines connected seems to keep it powered up on it's own (at least for a long while), I have to disconnect everything to get power to cycle.

Overall Review: When one port went dead on my 4-port Trendnet, I upgraded to 8 with this one. Don't know which 4-port Trendnet KVM the other reviewer had, but my old cables work fine at least with the video and USB. Mine was a KT-423, which also has PS/2 capability at computer end. Haven't tried that since it's not a listed feature and I no longer need it.
