It is the Omnifixo helping hands. My friend told me about it. It's pretty dope.
That one is 90x180cm and you can combine, stack, move the arms whatever way you want. They are static when you move so are able to be angled and stay that way. They can also be a ground to the board.
I was getting frustrated with my helping hands with the tentacle arms and the old classic one I wasn't going to spend money on.
The magnets on the tentacle one was too strong and hard to move. The clips themselves cut into wires. The Omnifixo doesn't do that.
I also bought a circuit board holder as well but got frustrated with it.
Here is their video showing the features:
