Easy install and operation with OPNSense. Reasonably fast operation with hardware for the money, too slow in my tests to run squid proxy with filtering if speed/heavy usage required but I don’t really need that.  It is very reasonably warm in operation but I added an external usb quiet free standing fan to move low speed air across it and case stays cool to touch.  Very satisfied, and recommended. Been running a month now, absolutely no issues.
