I'm a product specialist. In the past 8 years, I have been devoting to KVM series and other audio & video product. My focus is on those top selling item on Amazon. I personally order them and compare them one by one from chip solutions, looks, features, price, using, and seller reviews. 

​

The top selected may not be the best one if my analyzation is not enough, but they are worthy. I hope my recommendation may help you find the right one for you.
