As a huge fan of automotive, I have been using this product for a week and it really improved the hydraulic response in my car`s steering system. As a result of my tests, I determined that this is a must-have for any performance enthusiast .The installation process was a bit challenging, but once I figured out what to do, it was a breeze. The only downside I noticed so far is that it's a bit pricey compared to other similar products in the market..
