Comes in a small cardboard box with a basic manual. Used this to test a brand new bottle of DOT 3 and it came back with 0.4% I found this a bit strange as I would of thought that a new bottle would read 0%, I then tested this on plain water and it read 2.6% again I would think it would read 100%. Used this on my car next with fluid that's about 2 years old and got a reading of 2.6, I have no way of testing if the reading are accurate but after 2 years of the fluid being in the car I would say its pretty close?Cons:- The battery spring on the positive side(+) is too large for the AAA battery and doesn't make contact. I had to wrap a thin metal tab around 1 battery to get it to make full contact.I cant fully recommend this because of the battery issues, I took the time to figure out why it wasn't working most would just return it and for the accuracy of the reading I would think a fresh bottle of brake fluid would read 0 and water would show 100%. that was not the case.
