They are good leads but not the best. They do have strength, and are a high quality lead. There is at least on flaw in them, and yes I do use them. The large finger guard on the end makes it impossible to get into tight spaces. They are a good lead though.
Here ya go hoss. Oldaker is a USA company so they understand issues with test lead function...
Believe it or not it's UL that has pretty much dictated the use of the finger guards. When I worked on a project designing a high quality DMM, one requirement was it had to meet U.L requirements since many of our customers required UL certification. And once voltages get above about 40V, U.L gets there fingers in the pot. About the only way to meet some of the isolation requirements for the user was to put finger guards on the probes.
I suspect that any DMM leadsets sold that meet U.L will have finger guards.
And notice that the old exposed banana plug on the probes is also gone. It's now usually recessed into a shrouded connector. Again, necessary to meet U.L. and in reality probably not a bad thing. You don't want the probe coming loose from the DMM when connected to a hot lead and have an exposed banana plug dangling around!!
