Great tool for anyone to use!
This is a very quick and easy tester to know if your brake fluid needs to be changed. This tool can save you a $80-150 service with a 30 second process. It will pay for itself with peace of mind and not doing unnecessary services. Read full review

Brake fluid tester
Really cool little tester. I tested my cars 5 year old fluid and it tested bad 4% water. I tested a bottle that was opened and the cap on tight that was 5 years old and it tested 1-2% water. I tested water and of course it tested as water. I tested known good fluid and it tested good. So I have quite a bit of confidence in it now. Great to give an idea of when you need to service your car. I also like that it takes one aaa battery that’s easily obtained, and not stupid button batteries. Read full review

DO NOT RECOMMEND THIS!
To test this I bought brand new brake fluid and it tested with a red light reading then tested the brake fluid in my car which was a year old and it tested ok! A friend had some paper brake fluid test strips and the new brake fluid I bought tested excellent while my car's fluid fair.Too cheap to give accurate readings.Read full review

compact and useful
Does what it is intended for. Measuring moister in hydralic fluid. Not sure about accuracy, but if you have moister in hydraulics Brake fluid , you will want to replace it anyway.

great value and accurate
For the price I wasn't expecting much but I figured what did I have to lose. It actually turns out it is pretty accurate. i tested it against 3 other much more expensive testers and they all came up the same. So, I trust it now.Read full review

easy to use and works well.
It works very good. I was going to change the brake fluid after hearing that it collects moisture. But the light was green and the brake fluid was clear. Saved me 150.00 dollars.

Happy with the product
works like I expected it to. Have used it about 2 dozen times on old fluid and brand new fresh bottles and bottles that were only days old since opened (but cover screwed back on). results have shown what I would expect, less than 1% moisture on brand new bottles- even the ones that look slightly "dirty" colored and 2% in just 2 days open and capped and pegged on most of the used stuff I have checked, with unknown lengths of in the resevoir on most. but a 2018 ford focus is likley to have fluid from 2018, so 3 years and already pegs this moisture meter, shows you really do need to fully flush more often that every 3 years!Read full review

I do not recommend this product.
The two metal feet used to measure this are not firmly attached to the body of the pen. In the second measurement, one of the feet fell into the brake fluid, and as the fluid container was tilted, it slid along its bottom and reached the opening of the master brake cylinder. To remove, drain the brake fluid and separate the fluid container from the brake cylinder. Too long and unnecessary surgery.Read full review

Get one, if you have ANY interest in maintaining a vehicle.
This is the only way to test your brake fluid! Not mak unnecessary fluid changes, and don't fail to service when needed, or listen to an upsell from a drive through oil change. Quick, simple and seems very reliable. A great bargain.Read full review

It works now and I am very happy with it
I tested my brake fluid in my car and it was in the ok range. It was last change about two years ago. Then I check some brake fluid that I had in a bottle and it tested in the new range with a green light.Read full review
