According to my experience, this socket is not worth purchasing for heavy duty work in an industrial setting. Although it may work fine for simpler tasks the construction quality is poor and it broke easily during use..
Pros
may work for simpler tasks.
Cons
poor construction quality, not suitable for heavy duty use in industrial and scientific settings.
I have been using this set every day for the last month or so. The tool showed no signs of premature wear. The socket fits my percussion gun snugly and doesn't fall out after a use or two like other brands. Thanks to the large range, you can save yourself the use of an extension cable. I recommend this product.
