Works perfectly. Tested on DOT 3 and 4. Tested on a new bottle and showed less than 1% water, tested on old vehicle and showed over 4% water. I saved me from a bad shop job, I tested my brake fluid and it showed over 4% moisture took it to the shop and said the brake flush was never performed after they tested with their machine they agreed and completed the flush retested and all good. Invaluable tool, now I know not to take my cars to that shop.

Makes testing very easy - hint - don't dip all the way into the fluid or it displays 4+%. Just put the tips in half way. Can save a lot in repairs identifying contaminated fluid.

The product does work but kind of expensive for a device that you will use once in a while.

Purchased for my husband, who is a "do-it-yourselfer" and he is extremely happy with this new "toy". He believes it is as good as what the local stations use.

Excelente producto, cumple con la verificación de agua en el lÃquido de frenos. Cuando muchos mecánicos sin saber, indican que está bien el lÃquido porque está transparente. Siendo que tiene agua. El dispositivo es muy confiable.
