Summary: I can't honestly rate how it works because when I went to set it up, it had no power supply. Nothing on the box or in the listing says anything about requiring a separately purchased power supply. The gig switch I bought at the same time came with the power adapter.
Summary: Doesn't even come with the 5v DC adapter that is needed to power it. You would think an 80 dollar kvm switch would at least have EVERYTHING you need right out the box. Now I have to wait more days since I have to order that now. Disappointed.
Summary: I only unpacked it today, but it works great out of the box and has a sturdy construction. I was hesitant when picking a KVM but from everything I read about this one, it seemed like it would fit the bill. I have one Windows box, and 3 CentOS boxes all connected and can switch through them.
I highly recommend the SVUSBPOWER spare 4V DC power adapter from StarTech ...

Summary: I highly recommend the SVUSBPOWER spare 4V DC power adapter from StarTech for this. It doesn't make sense not to use it. Even though this product supports power through VGA or USB (can't remember which one), it did not work well for us and so I only gave this product 4 stars. Otherwise it's super!
Good equipment at a fair price. (4-port USB hub! YAY!)

Summary: This is a pretty good unit. I didn't know, however, that it required a special female to male VGA connection. Toher than that it works well. I does not come with nor require a power adapter (unless the computer your working with does not have USB.
Summary: I do not use the video portion of this switch as I have a need to see all PC monitors at all times so have 7 monitors on my desk. The use of the switch for mouse and keyboard were my chief reason for purchasing this switch.
Summary: Purchased this KVM switch less than 6 months ago, and it is already malfunctioning, giving intermittent connectivity. I contacted Startech about it, and they recommended I replace the cables, But even a cable I never connected that was still in the bag failed intermittently.
