Brake Fluid Tester 5 LED Car Vehicle Auto Automotive Testing Tool For DOT3/DOT4

Ok

Ok

This gadget is an important tool for checking brake fluid! If the proportion of water in the brake fluid container is too high, the performance of the brake system noticeably decreases! This can have catastrophic consequences for the safety of the car occupants! With this brake fluid tester, the functionality of the brake fluid container can be tested at any time!

The testers are also OK. Both of the last orders are defective. One of the batteries needs a new one every 2 days. The other one can no longer be switched on. I hope the two new ones last longer.

I haven't used it yet but I think it's good. The package is in order and the device looks good. I put the battery and the light came on. Everything is OK. Revin- I tried it and it works very well.

The tester is super useful and accurate, verified by me ... RECOMMEND WITH CONFIDENCE.

It is not as described and an air freshener

very good

On the brake it shows green, on the water all the LEDs are on - it seems to be working.

I haven't checked it yet, but everything seems to be OK, it corresponds to its quality
