In my experience the cheap jump leads are a waste of time if the

I made my own jump leads from four heavy duty clips and two runs of
arc welding cable. They are capable of jump starting a car with a
completely flat battery, but I haven't found any ready-made sets that
will.

I managed to buy a ready made set but they do amount to just what you
made, if I couldn't have bought them I would have made my own as well.
BTW they are also a good length, about 3m IIRC so can jump a car when
parked next to each other and the batteries on opposite sides. They are
about 20 years old now, I wouldn't want to price them up these days with
the price of copper being what it is.

Mine are made up from high amp cable like is used for electricity
meter tails etc.
