I am so impressed. I did watch and jewellery repair for 15 years and I bought this kit bc a fire destroyed all my tools. There are alot of decent tools in here and some have features Ive never used before. The 3 prong wrench tips screw in, alright!!!! The watch press dies are tougher plastic and actually screw on like they are suppose too. The only thing I need to buy are metal dies for the press, cant use plastic all the time. Super impressed compared to the price. Id recommend it and now I can fix all my watches again.
