Review on Accurately Test Your Car'S Brake Fluid With Our High Precision Brake Fluid Detector - LCD Screen, Audible Alarm, Suitable For DOT3 DOT4 DOT5.1 Fluids by Antonio Santiago

This is a great little brake fluid tester. It has a build-in light and works on most brake fluid types. I like the flexible tip for the tester as many vehicles have the brake fluid reservoir right against the firewall and out of reach. I've used old testers like this but had to have a different test for each type of brake fluid which was very ineffective. This test solves that issue and priced very well for the features and accuracy.
