I have used various KVM switch boxes over the years, some that were really cheap manual boxes to very expensive and high quality KVM’s. One product kept breaking the audio/mic ability and I had to keep getting replacements for the device. Another brand worked really well, but the company is lagging on the latest technology, like DataPort connections and dual monitor / dual computer KVM's. The CKL CKL-622DP model was easy to setup and pretty much hit the ground running, but I did have an issue that was not portrayed in the web site or manual, but was corrected by customer support. So, if you have any issues with setting up the KVM, I encourage you to contact their technical support staff.Several things I like about the box are it was built well, though putting all input ports in the back would be my preference, but that is not the norm. I also think the power supply could hold the USB cable in better as it is pretty lose and if in an area of traffic, could become easily unplugged. It has a power switch in the back that during troubleshooting was a blessing. My other KVM’s require I remove all connections and then put them all back in. Having a dual monitor / dual computer KVM Means I no longer have to change my monitor settings from one computer to another as I did with my single monitor, dual computer KVM. The product is easy to setup and easy to use manually and comes already setup for KVM control from the mouse. I also liked that I have 4 data ports to use and audio / video jacks for both computers to play through one set of speakers. One of the issues I came across is my keyboard display lights either stay on, no matter the selection or are not on at all, like my Caps lock light. I will contact tech support about that. One other thing I am tolerating and not used to is the delay time between switching. The aforementioned expensive KVM boasted of DDM technology which does make switching between computers almost instantaneous. But, you do pay for that convenience. So, if you don't mind waiting 10 seconds for screens to show up and the keyboard and mouse to work, it is a great KVM box and I recommend it.
