### ⭐⭐⭐⭐⭐ Works well
*by B***E on January 6, 2026*

It seems to work well, tried it various times, and no difference in outcome. Aside from the battery door (Battery not included, just a heads up) being a bit of a task to remove, it's a good little tool.

### ⭐⭐⭐⭐⭐ Good solution.
*by R***E on September 29, 2025*

Does the job and good price

### ⭐⭐⭐⭐ Good enough, fast but variable readings, fair price.
*by G***S on August 23, 2024*

This is fast and easy to use. Display is bright. Performance and quality in terms of accuracy is hard to measure. It can definitely tell the difference between brand new fluid and water. Those results were exactly as your expect. On my used fluid, the results ranged from 2-4% and I took several tests to conclude the mode reading of 3% was probably fairly accurate. For the price it's a reasonable value even if not professional quality. Battery required is a single AAA, and the re-closable bag is a good place to store both between uses.
