5 LED Brake Fluid Tester Pen Automotive Testing Tool Car Vehicle Testing Tool Brake Fluid Tester

The body is made of fragile material. When you open the cap, it breaks. When you press the button, the case cracks. I had to seal it before I even had time to use it. The presence of water in the brake fluid is a good indicator. I checked it in different cars.

The product arrived, I have not tried it yet, the device is pleasant to the touch, I will add a comment when checking. I recommend the seller. I checked, it seems to be working. It glows red on water, green on brake fluid.

Good quality. But there is no performance. It shows the same whether the brake actuator is new or used. Therefore -1 star

It works, but what it shows and why is not clear🤪 I tried vegetable oil, jam, and in my mouth - it works everywhere.

Normal device. I checked the brake fluid of myself and a friend, everything is normal, I can drive.

Haven't checked yet I checked, everything seems to be working so far
