Don't worry, I'm not the type of person who doesn't understand what a product review is good for. I bought one of these for $6 or so. mine didn't work. The seller is well done, he returned the money, and I threw away the goods. Not feeling sure about ordering another one, I saw a few bucks more, like $10 so I could get a 4-way switch. I've only connected 2 computers to the same monitor, but this way I have options for the future. and I didn't actually have to rob a bank to do it. You don't give a single star in a product review because the product doesn't work. A lot of people don't understand that! I just don't understand this product when a 4 position switch costs quite a bit more money.
