good product and resistance of the cable is zero ohm (or at least to small to be measured by my ohm meter) and with the 5 cables connected to each other the total length is less than 1 ohm, very satisfied.

These are very high quality test leads, better than many of the leads we use in my engineering lab. The description says PVC insulation, but it feels more like a silicone; either way it is a high quality insulation. They are extremely flexible with zero rigidity. I have not tested how much current they can handle at any given voltage, but already have good confidence in them after some preliminary load tests. The banana terminals on them are excellent, fitting snugly into ever terminal I could find, only possible upgrade would be if they were gold plated. These definitely exceeded my expectations and I will likely buy more in the future.
