Review on 🔁 Enhanced 4 Port KVM Switch HDMI Dual Monitor Extended Display - 4K@30Hz, 2 USB 2.0 Hub, Wireless Keyboard & Mouse - Hotkey Switch Supported - 4 in 2 Out - Powered by USB by Dylan Goins

I've been using this in my home office for four months. I use it with two 1440p monitors, two Windows 10 computers, a Linux computer and a 13" MacBook Pro. Everything works fantastic with one exception - the Mac refuses to recognize my external mouse and keyboard when connected via KVM. My workaround was to get a USB a/b switch (I got this one here: https://www.amazon.com/gp/product/B01MXXQKGM/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) so I just need to click it when switching to/from Mac. A little annoying, but not critical. The keyboard shortcut to switch inputs is very handy as my KVM sits quite far under my desk so accessing the physical buttons is awkward. Overall I'm very happy with it so far!
