### ⭐⭐⭐⭐⭐ The closest device to a mechanics shop tool and very accurate after.
*by G***W on August 8, 2025*

### ⭐⭐⭐⭐ Works on standard fluid
*by C***Y on February 15, 2025*

I bought this to test the racing brake fluid in my vehicle and it does not register any racing brake fluid. I have tried DOT 3 and 4 non-racing fluid and it detects the moisture just fine but when I dip it into the racing variety of the fluid, it reads nothing and acts like it does not detect it. Something to keep in mind if you’re using this for Performance capacities.
