I just used these for the first time last night with my Fluke 87V meter to test output from a small solar panel. They were just the right length to get into the female connection after unplugging the output lead from the panel. The leads that came with the meter are great, but they are too short for this type of usage. Worked very well. I would recommend these if you need to get into an area that is inset or has other protected items around it.
