I ordered this vevor 3.75" 4 jaw wood chuck in late 2022, mine was well balanced & holds my workpiece much tighter than my old lathe holds its 1x8 spindle. The nickel plating is extremely thin and peeling, the jaws are a little loose when open, much like in the above user's video, but I mean, they do tighten up when you...tighten them up. The only other chuck I was considering was a nearly identical (but presumably better machined and QC'd) PSI Barracuda at 3x the price because so many reviews said the cheep ones wobble. I decided last minute it was worth risking a return to possibly save 2/3 of the cost, and in my case it paid off. I can see other users have had problems, so I'm guessing the machining QC is the biggest problem.
