Query: Awful

I have used many different kvm switches at different jobs and have never had a problem. I then purchased the iogear kvm for my home computers. I wish I had bought a hammer as well, because I would of smashed that piece of ****. It caused nothing but 5 hours of fustration.First of all, turning it to "hot key mode" was as fun as ripping a toe nail off. (You have to press and hold this key for two seconds, then press and hold a second key for one second while still holding key 1. Then remove key 2 while holding key 1. Then within a second let go of key 1) In an hour I got it to work twice.When I finally got it to work, it opened up a whole new list problems. Whenever I would switch screens, I would need to readjust the aspect ratio of the monitor. I could not get both the keyboard and mouse to work simultaneously (either one of the other). I tried every combination imaginable.The sound also wouldn't play properly. I could go on and on.RUN, don't walk away from this technological travesty!
