Good tool to have.
Simple, straight forward. Works as intended. Makes checking the fluid in the car or on the shelf a no brainer.

Great product at good price. Everyone should have one
Great product bought to keep repair shops honest - it worked and saved an unnecessary brake fluid change I knew intuitively wasn’t needed.

It makes sure your car breaks without breaking the bank
It feels kind of cheap but has never given me any issues, the battery live is very good and can read many different types of brake fluids. It's a good price and reads very accurately compared to other higher end brands. It does a good job for what you're paying for!

Seems to work good
Just got it today. Tested 2 vehicles. Seems to be pretty accurate so far. Always keep fresh "aaa" batteries in the tool.

Easy and accurate
Installed a AAA battery, dropped it in the brake fluid reservoir, read less than 2% water, Done. Easy peasy. Digital readout is clear and menu buttons are simple.

Great addition to my automotive tools
I bought a cheaper pen type tester first, but thought it gave suspiciously high readings in my cars that had their brake systems flushed not that long ago, so I bought this one to compare and it did give lower readings. Both units correctly read zero water in freshly opened fluid, so then I tested a few samples to which I added progressively more water. The pen type always read higher and I think the reason for this is that it's one-size-fits-all for DOT 3, 4 and 5 fluids whereas this one has an option to select the fluid type. I did get higher readings with this unit with DOT 4 and 5 selected in the same samples, so that seems to be the explanation. All of my cars use DOT 3 fluid, so being able to select is a good option, worth paying a little more for.
