I have a nice collection of machinist and general fabrication vises in the workshop, mainly for the milling machine, CNC and bench work, accordingly I am pretty fussy with clamping, I was after a basic vise for soldering connectors, glueing parts and holding probes, etc.
Aldi down here had these for about 15 bucks in either suction base or clamp base, skeptical at first I looked around and everyone else was selling them for double that price, I got two suction base units so when she's not home the dinner table transform's into my work area.
I had no intention of using the suction feature, why ?, because I don't need it and honestly it sucks.
Got rid of the rear clip off the leadscrew for extra travel (85mm) and maintenance, removed the steel jaws and filed the cast to re-seat and improve jaw alignment (mine were crap at first ), added some lead plates inside the base as the units are top heavy, later added 1mm strips of sheet rubber between the steel jaws and cast to improve self alignment for holding small pin's and the like.
One unit had two sets of the rubber soft jaws in the box, bonus.
Anyway, others probably don't need to do all this as the units are ok out of the box, but as you can see there is room for improvement. Also the Panavise down here is just ridiculously over priced IMO.
General Summary: good value, handy gadget, has warranty.
