### ⭐⭐⭐⭐⭐ Love it, although a bit pricey
*by M***E on September 17, 2018*

Good stuff, puts the spring back in the step of my old car. It also has a unique type of lubricant that they claim modifies the surface of metals. Not sure how that works but it is intriguing.

### ⭐⭐⭐⭐⭐ Quality
*by G***A on May 24, 2020*
