I've always wanted one. I do a fair amount of soldering. Mostly little things. This "helping hands" device keeps small objects close at hand so you can solder them accurately. This tool is configurable in every dimension. Wing nuts are used to tighten connections. The magnifying glass offers 2.5x magnification. My only problem is that the connections with the wing nuts are not very tight. So there is still a little play in the system.
