In general, the set is really useful and of a great quality. Not only did it come in handy when I was working on my car, but it also helped me out when I was cleaning the house. Perhaps the SATA series tool is the only one that is of higher quality, and I highly recommend purchasing it. Various advantages: I was able to shake the entire car with the assistance of this set, as its quality is outstanding throughout the board, both in terms of the heads and the keys. Even while utilizing the key-for-key hook, the hooks do not bend or break. However, the heads of the hooks can easily lick the metal if they are taken for a hard break. The casing and the tool were able to survive the fire, the water, and the copper pipes. Having this drawback: the quality of the nozzles for screwdrivers and hexagon sprockets leaves a lot to be desired; some split right away, while others just lick off; after two years of use on a large ratchet, the tongue for switching the direction of rotation fell off; the nut turned out to be 6 on the bottom; and the tool began to rust. of the flaws that occur when transferring temperatures, condensation forms and the tool begins to rust.
