After reading other review for this product I was a little reluctant to purchase it. I searched for other affordable alternatives but could find none. It is a well made imported (Asian) product. I am very happy with the performance and quality of the chuck. It is well make and an excellent value for the money. I also purchased the flat jaws and am equally happy with them. If you are looking for a product that is engineered to the highest possible standards and is manufactured in Switzerland by the finest toolmakers in the world, it probably is not for you.
