This wrench set WAS a complete letdown. After I put it to the test on multiple occasions, I found that the tools were poorly made and lacked durability. Although the price may seem tempting, I wouldn't recommend this set for any serious industrial use..
They are rough, embossed, thick, irregular and not smooth. I do not recommend this key phrase to anyone. they cost a maximum of $5 and I paid $28. I'm just in time so I need to try and get them working for my project or I'd be returning them! Many Thanks
