Had one for over five years and still works. Good for light duty tasks like filing, drilling wood, and similar things.

In my experience, the helping hands tools are too flimsy to do any real work on a board with them. I've always preferred to have a solid table clamp similar to this. You will be able to hold a board, solder on it, probe around on it with a scope or multimeter, etc. I haven't seen many helping hands tools that allow you to do that.

Separately, I would recommend a Weller or Hakko. I have a Hakko FX888D that works well and was relatively cheap (about $100). A good soldering iron will have good options for tip sizes AND provide heat to the tip making your soldering work nice and easy.
