Very high-quality set as in all Proxxon products. The sockets fit very tightly on the ratchet, which for me, having worked with several, is one of the best. As for durability, I believe it is a very robust set provided that the torque limit of about 10Nm is adhered to, because some unfairly judge quality tools because they do not follow the manufacturers' specifications. You cannot loosen a stuck screw with a 1/4 ratchet by applying too much force because it is likely that the tips will bend or even break. You cannot know exactly what 10Nm is, but you understand it empirically. For amateurs, I believe that most will realize when the tool is working at its limit of durability.

Ultimately, for its price, it is quite expensive. If one considers that a similar collection can be found in supermarkets for 10 euros. I only recommend it for tasks within the house and in no case for a professional
