This fancy and ultra-adjustable PCB holder was recommended to us by Collin, who is not only a maestro at soldering but also has impeccable taste in furnishings, so we just had to get these in stock. Not surprisingly, we agreed with Collin that this is a really great PCB holder. Got a big ol' clunky circuit board that needs rework but is too big for your standard everyday vise? Not a problem. Have to do lots of through-hole where you place the part on one side, then flip over to solder the other? Easy peasy lemon squeezy.
