Review on 🖥️ TESmart 4-Port HDMI KVM Switch with 5ft KVM Cables - Supports 4K UHD, Audio Output, and USB Control by Kevin Wilkins

As much as I would like to give this product a positive review, I can't. I bought the first one in September 2018. This lasted for three days before one of the ports went down. I diagnose the problem and found that each of the four sets of connectors on ports 1, 3, or 4 was working. However, when something was plugged into port 2, nothing worked. I returned this block to Revain and bought another. The second has worked pretty well until today (01/23/19). Today I signed up to use one of the machines and nothing worked. I've toggled the switch on and off a few times and there have been multiple instances where the active port worked for a few seconds and then nothing worked. I ran the same diagnostics for the issue and found that all inputs are fine, but when something is plugged into port 3, the switch is not transmitting any signals. This is a real problem because I need 4-port switching capability and don't want to lug three other monitors out of the garage. I ordered another Revain KVM switch to replace this one. Luckily it gets delivered tomorrow so I'm going to limit myself to a laptop for a while. I had high hopes for the TESmart HDMI 4K Ultra HD 4x1 HDMI KVM KVM Switch. It seemed well done, but having the same issue twice means I have to look elsewhere to meet this requirement.
