## Customer Reviews

### ⭐⭐⭐⭐⭐ nice to have, working well on rusty euro car.
*by J***N on December 12, 2025*

Holding shape after working on some pretty stuck bolts.

### ⭐⭐⭐⭐⭐ Invaluable tool for my Audi
*by S***I on September 9, 2024*

Really hated having to get another one use tool, but I did anyway because I needed to remove one bolt for a single job. Then I found I needed it again for many other bolts on the car. Very glad I got this set.

### ⭐⭐⭐⭐⭐ Great value
*by S***A on February 5, 2024*

I needed this for a (likely) one-time project to remove/replace a steering wheel bolt. Very reasonable price for a set of tools of good quality. Certainly MUCH less than having dealer do the simple work I could do at home with the right tool.
