Works great. Tested for DOT 3 and 4. Tested on a new bottle and showed less than 1% water, tested on an old car and showed more than 4% water. Saved me from a bad job at the shop, I checked my brake fluid and it showed over 4% moisture, took it to the shop and was told the brake flush was never done, after checking their car they agreed and did a recheck rinse and all is good. An invaluable tool, now I know I shouldn't take my cars to this workshop.
