The product seems good quality but I am rating 3 because the description is misleading. I was seeking a self-centering chuck. I saw the keyword "self centering" in multiple ares of the product description, and I saw a breakout diagram in the product images (in two locations) where a spline disc is shown to drive all four jaws together, effectively giving self-centering function. But, the product has FULLY INDEPENDENT jaws, and it has zero functionality of a self-centering lathe chuck. As a beginner with these parts of tools, this description is misleading and I wish Vevor would include a PDF manual in the downloads so we can verify exactly what we are getting before ordering. My photos show how the jaw moves fully independently and the splines that drive the jaw are not interconnected.
