Vevor is going to be just like anything else from China, hit or miss. I don't know their chucks in particular, but I have had other Chineses branded chucks cross my path and I just kept moving... I do have Bison chucks, they are excellent. It will be also dependent on what you are looking for? If its a good quality chuck for low cost, you will probably be disappointed. But if all you need is an okay chuck for general work, it could be a good deal. I recently bought a Vevor power drive for my mill. At only $125.00, It's not bad for the price, but not as good as a top brand.
