    useful and practical
  

*by A***D on Reviewed in the United Arab Emirates on 15 March 2022*

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
