Hi
Yes, I got similar clamps
https://www.eevblog.com/forum/testgear/gold-plated-test-probes-any-good/25/No, they are not the best but they work.
Do not worry, the gold plating is ok and so far has not flaked off.
You will actually limited by what will fit through the hole of the clamp housing.
I used a small uk based firm, they only supply 1 type of silicone test cable. So I just got that.
Everything they supply is good quality so I do not have to worry.
Think about strain relief. I put cable ties on my cables so the the cable tie is against the hole in the housing.
I used mine at work this week. Managed to measure 55 micro
