Excellent product! The brake fluid moisture tester arrived quickly and works perfectly. It's easy to use, accurate, and gives me peace of mind knowing my brake fluid is in good condition. Highly recommend this seller for fast shipping and quality products. Thank you!

Reasonable price, good delivery and it seems to work. Used on a few vehicles, all but one tested OK. Point is the tool did pick up on the moisture. Also tested on just water and it reacted as expected. A good addition to my garage.

This brake fluid water tester came very quickly, but did not really operate as I expected as it shows newer brake fluid to have water. All brake fluid I tested, gave me red lights. I didn’t try buying a brand new bottle and testing it but the brake fluid that I had just changed in my Jeep showed that it had water in it and I don’t think that is the case. I found out later that most testers of this type are not veryaccurate.  with that being said it works for what it is intended to do.

    Some calibration needed

    For the money, this tester is a good deal. It does require a little calibration, though. Mix up a small amount of new brake fluid with 2% water using a graduated eye dropper. Dip the tester into the solution and see just how deep the probes need to go to register 2% and no more. Tape off the probes with electrical tape at the appropriate depth. I found 3mm enough to correctly register the 2% mixture. More than that resulted in an over-estimate of the water content.

    A qualified endorsement

    I'm giving this item a qualified endorsement. I had a long back and forth email conversation with the vendor I purchased this from. He was very cooperative and the conversation is quite extensive so I'll just go ahead and include my final takeaway from working with the tester. Bottom line: > These testers are very inexpensive and that's possibly a point that should not be forgotten. > Quality control appears to be a problem, as I encountered on the second tester being unusable with the battery cover in place. > Reliability of readings as seen in these tests appears to be potentially questionable depending on the brand of brake fluid used as the manufacturer claims certain brands can result in inaccurate readings.

  • Slightly of poor quality, but can be use for indication only.

    The product is working eratically, and the battery cap is not closing when I put a battery inside . Still I wonder if I could use it for as indicative only.

  • Sometimes testers work, and sometimes they don’t

    I thought I would test my brake fluid, so I purchased this item thinking that it would work, but it gave me bad readings on brand new brake fluid in a bottle and then when I looked it up online, they say that there isn’t very many low priced accurate products for this type of testing.

  • Double Check Your Dealership

    My wife and I had the typical experience at a car dealership when having a service done on each of our vehicles (on the same day). They both needed a cabin filter (I'd just replaced them) and a recommendation to flush our brake fluid due to a 3% moisture content. I had them tested at a trusted auto repair shop and they tested good. I bought this because it was inexpensive and it gave me the same reading as the repair shop.
