One side has a magnet, and it firmly attaches the base board (steel). But the other side just has the pogo and is fixed there just by the weight of the thing. It works good if there's enough "bite" and the rest of the system applies force the right way. If not, we'll, it slides off.

In my case for example, it is excellent for test points but somewhat challenging with soldered SMD component pads and very challenging if the density is high.

If you're able to solder on and the signal can stand the stub, a little dot of copper tape on top of the IC and a tiny wire down to the lead in question and soldered on can help give an easier "hitbox". You can add the ground pad as well next to it and use the spring for the probe.

If I'm going to have to solder, I'll just keep using clamps on the end of the jumper wire...

Ah, that's really helpful.

I assumed they were those bendable wire things like old style podium mic stands. Those tend to sort of stay where you put them, but not very precisely.
