Above Kelvin clips, the weak spot is the plastic, I had 2 pairs where the grayish plastic gets brittle over time and cracked at normal used. Also their jaw biting power is not strong when measuring big DUT with big terminals like power resistor, big inductor and etc.
Better one is the one made by GWInstek, as its has better precision mechanic and built.

GWInstek Kelvin clips reviewAlso another model, below photo, is my fav and mostly grabbed clips as it has powerful jaw that made measurement process not fiddly at big DUTs or big leaded components, especially when we moved alot and sometimes bumped on the clips or even the wires can fluctuate the reading as the teeth moved abit. The metal and the clips teeth are quite strong and wont chipped easily when clipped on hard metal terminals. Also it has very simple mechanism is almost fail and fool proof, and the jaw biting power can be enhanced too if needed.
Both models are available at AliExpress.
