I like that I can put the optocoupler into the socket for open through pin tests. Can also poke the pins of the optocoupler with the four prong probe.Simple to test with LED light indicator. Green is good, white is bad.It has one function so it’s not like a multi meter which has many functions. USB-c charging port. About as small as a thick marker.
