Does not look like picture as advertised. You would have to use a sharp edged knife or something to open it. I am sending it back due to other comments about the battery cover and the inaccuracy of this product. Obviously a piece of garbage and not worth buying. The well-known YouTuber who suggested this will be contacted to tell him about his poor product suggestion

I use this tool on every vehicle inspection. Just because the fluid LOOKS bad,it doesn’t mean it always is. This can save customers money if it’s tight. This is a tool mainly used to sell brake fluid flushes, though. It tells you the percentage of water that makes up the fluid. Brake fluid is hydroscopic. This means that it’ll absorb water from the environment over time and it begins to turn acidic. This corrodes the lines from the inside out and the fluid loses its ability to work properly. Long story short – it’s a decent tester. The only problem I have with it is that sometimes the tool won’t be able to dip into the fluid because of the reservoir design. No tool is perfect all the time, and this one works just about as well as any other. Would recommend.

I saw this device suggested by one of my favorite car care Youtubers. Since I didn’t know how old the brake fluid was in the used vehicle we recently purchased, I thought this would be the perfect way to find out if it needed to replaced or not. When the device arrived, there were no instructions included. I know it needed a AAA battery, but the battery cover is VERY difficult to remove. After using a pocket knife to remove the cover, I got the battery installed, and 1 green light appeared when the top button was pressed.
I went outside and opened the brake fluid reservoir on our vehicle, pressed the button and dipped the metal tips into the fluid. Instantly, ALL of the lights went on; which, according to the guide printed on the side of the device, meant the fluid needs replacing. All good, right?
Not so fast… A few days later, I bought a brand new bottle of brake fluid, and got everything ready to start replacing my vehicle’s fluid. For the heck of it, I decided to re-test the fluid, and this time I only got ONE green light. So, it’s NOW saying my fluid is OK? I cleaned the end, and tested it again, this time, I got one green and TWO yellows. I moved the end around in the fluid, and the number of lights was all over the place. I decided to test the brand new fluid, and it instantly illuminated ALL of the lights. This device has serious issues…
I was going to try testing one of our other vehicles, but the reservoir has a small grid that doesn’t allow the metal probes to get anywhere near the fluid level.
Oh, and don’t dare get fluid on the plastic part of the device. Where ever brake fluid touched, the white printing that shows the light guide, etc., has smeared or rubbed off.
I would send this piece of junk back, because it’s still within the return period, but the cost of time, effort, and shipping just isn’t worth it. Bottom line, avoid this thing…

I found this tester brake fluid tester does a good job. I tested two of my vehicles.
I performed the test on my newer Toyota, and it did not need new brake fluid as it read at most 1% water content. My older Toyota, and it read in the 3%~4% zone noting it needs to be changed.
This tester gives me a good idea of how my brake fluid is doing.
– I found it to be easy to use
– I found it alto be accurate

This tool makes me money for such a small investment. Contamination of brake fluid from moisture is not good. I’ve seen components corrode and break on older vehicles. I’ve pressurized vehicles and bledd bleeder screws that have not gotten regular brake flushes and the moisture content is almost always present I’m the master cylinder after using two or three quarts and the fresh fluid. usually the fluid in the master cylinder stays dark in color and I’m telling you, the fluid coming out of the bleeder screws looks clean. I’m going to begin testing the fluid coming out of the bleeder screws if they are convenient to catch and if the environment isn’t excessively humid. Anyways, the way I test the pen is test fresh brake fluid in a small sample then spray a mist of water with a sprayer bottleand monitor moisture ratings with the pen. I understand you can test brake fluid with a multimeter as well but this is so cheap and convenient. This brake fluid tester and then a good flare wrench set and l maybe even offset/modified offset wrenches just in case could be good for not having to remove a tire to open bleeder screws on vehicles equipped with electronic parking brake systems. I’m paid .5 labor which means the tool pays for itself after the first brake flush, so it’s a heavy hitting money tool. It’s very good guys and gals. Like an amazing tool. I like to purchase a new one every few months cause I basically test every vehicle during regular maintenance. Once it’s 4% or more then I suggest doing the maintenance. I’ve noticed vehicles who have regular flushes then the master cylinder is usually able to stay clean and keep moisture saturation low. There’s only one vehicle I tested that had absolutely perfect brake fluid inside the master cylinder which happened to be a Mercedes that likely recently had a brake flush. I was impressed.

Bought this awhile ago but didn’t get to use it until this weekend. The results were consistent with what I expected
– Tested on a 19 year old car 189K miles never had brake fluid change. It showed yellow > 2%. Good. I changed the fluid.
– Tested on a 7 year old car 72K that never had the brake fluid change. It showed green. OK, but i will change the fluid soon.
– Tested on 2 old dot3 fluid bottles i bought +5years ago and both showed yellow >2% . The bottles still had tight seals on but some how moisture still got in. Didn’t want to take a risk on old fluid so I threw them in the oil recycle bottle.
– Tested on new dot3/4 fluid i bought and it showed green which is expected.

This is a very helpful tool for verifying the moisture content of brake fluid. A good addition for diy or shops.
