Something to help hold the wire and circuit board steady helps too.
If you get the linked version... the base is a bit small. I glued mine to a 6 inch square piece of wood to give it a bigger base.
They also have a version with a soldering iron holder and lighted magnifier. This needs a bigger base even more due to the heavy lighted magnifier and the soldering iron. Just putting the iron in mine topples the thing without having a larger base attached.
I glued this one to a 1 ft square ceramic tile.
