Simple to Use Device That Works
Works great. Tested on a small sample first to confirm accuracy. Clean sample tested correctly. Added a relatively small amount of water to the sample and this device instantly recognized the presence of water in the brake fluid. My device says "Battery Tester" so I'm assuming this also works to test for presence of water in car batteries, but I've only tested this with brake fluid. Handy to have and provides peace of mind against water contamination in brake fluid whether the fluid is tested in use or to test a bottle of brake fluid that has previously been opened and stored for awhile. Simple to use, didn't need to reference instructions. This isn't a tool that shouldn't experience damaging contact through normal use, and the construction is sufficient for careful use, but dropping it onto a hard surface may cause fatal damage. Should be okay in a professional environment requiring frequent use, as long as care is taken- it is a measuring instrument after all.

Does what I needed it to, but for how long?
Seems to work. It is easy to operate, though I would have preferred a click on/click off switch, to a momentary on switch. Seems to be very cheaply made that needs to handled with care, rather than tossed in the tool box.

It really works …
Saw this and became intrested in finding out if it really worked. I was surprised that it actually did work. Tried it on 2024 Acura and it read that the fluid was normal. Then tried it on 2003 Honda ,;; it said rhat brake fluid was bad right away. I changed the brake fluid and. The. Re tried it. The fluid was then perfect. Great product
