It arrived and I used it right away on two different cars, one DOT 3 and the other DOT4. It was easy to use, and appears to be accurate. I found it very useful in determening the condition of my brake fluids. I would recomend this item to others.

Super Gerät , funktioniert einwandfrei und das für so kleines Geld.

Der ist der Hammer!

Consistent readings are reassuring. I'm "due" for a brake fluid flush, but I feel comfortable waiting after testing well within the Good range.

Quick readings. Easy to use. It’s worth the money
