Strengths: Includes 4 sets of integrated cables that only use 1 USB port on the pc, hot key and button switching
Summary: After some bad experiences with some other entry level USB KVM's, I was pleased with this device. The manual suggests that you restart all pc's and install this appliance, but I installed it hot with 2 devices. It took a minute or two, but it came to life. The only quirk was one server initially on boot up didn't see the keyboard and the bios gave an error, however I hit F1 to continue from the supposedly nonfunctioning keyboard and it continued on.
