According to my experience this star wrench set is an excellent choice for any industrial and scientific work. The keys are sturdy and made of high-quality materials, making them durable in any work environment. The design of the wrenches is ergonomic, which makes it easy to grip, and the storage holder is convenient to keep them organized. The only con I experienced is that some of the keys are a bit short, which can be a challenge for some applications .Overall, I recommend this set for anyoneSee full review
