## Customer Reviews

### ⭐⭐⭐⭐⭐ Good quality
*by D***R on September 5, 2025*

Work perfectly good

### ⭐⭐⭐⭐⭐ Great Product
*by E***L on July 30, 2025*

This is a great product and was exactly in the image. It fits perfectly to other sockets and ratchets!

### ⭐⭐⭐⭐⭐ I Expected Cheap, I Received Oil
*by D***E on November 2, 2024*

Very sturdy pieces that fit well with other brand tools and has most of hte lengths you'll need for basic DIY jobs/mechanic stuff. Can't stress enough I was impressed that these seemed to be strong pieces that won't strip. They feel slightly heavier than other sets I've owned, but it's not really an issue. They were also covered in a film of oil or grease which was odd. Only "complaint" is I wish they came with a case or carrying bag. I guess you can use the plastic tray they come in and put it into the cardboard box Amazon ships them in, but because of shipping my box was pretty beat up and ripped when I opened it. Still, the store page doesn't claim they come with a case so you are in fact only paying for the tools, which are still very good.
