### ⭐⭐ 







  
  
    it break after some use.
  

*by C***W on Reviewed in the United States on December 29, 2019*

Low price, easy to use. I am not sure its accuracy. As when ever put the stick into the brake fluid reservoir, it reads as ok. And the fluid has not been changed for nearly 2 years.As did a test to put it into water, it immediately went highest.The most unsatisfied prospect would be after like 2 uses, the plastic seems to be corroded, and brake when remove the cap.I would definitely wish I could have a better quality tester.

### ⭐⭐⭐ 







  
  
    Works but battery cover pops off
  

*by T***. on Reviewed in the United States on October 27, 2019*

This tester works fine, I even tested it with a sample of new brake fluid and a measured amount of water to see if was reasonably accurate and it was, certainly for the price. But, it is very aggravating because the door that covers the battery compartment does not latch firmly and is always falling off.  I was even demonstrating it for a friend and the door popped off and fell into the brake fluid and had to be fished out.  I solved the problem by putting a piece of tape over the door, but this is not right for an item that is 2 days old!
