Brake Fluid Tester Universal Car Tester Pen auto Vehicle, 5 LEDs Brake Fluid Brake Oil Tester Moisture Oil Testing tool Vehicle Diagnostic tools

I was confused and doubted that my car’s brake fluid might need to be changed.. But with this device I made sure that the oil is excellent and does not need to be changed.. To make sure, I tested the device in a glass of water.. It gave me the red light completely. This means that if the brake fluid has moisture or Water is bad and needs to be changed

Helped me alot in checking all my cars brake fluids quality. And had to change the oils coz they were old and bad. Recommend product!

The gadget looks fine and of useful. However the battery lid is loose and doesn't close properly after fitting the battery.
