Review on RKURCK AC 125/250V Push Button Reset 20A Circuit Breakers Thermal Overload Protector With Quick Connect Terminals And Waterproof Button Black Cap(5 Pcs） by Tom Motko

Black rubber grommet over the switch makes it impossible to see if the switch has tripped. Some others come with clear seals. Otherwise they seem to be doing their job. I don't see anything where they outshine other switches of the same type or differ in any way; They are all very similar to me (perhaps most are indeed similar, just branded differently).
