Accurate Brake Fluid Quality Tester

The item arrived within the stipulated time, it looks to be made of good material, it is very compact, just need to test it to see if it fulfills its function, and if so, I recommend this item and the store 100%.

The device works, although it was difficult for me to find how to insert the battery, but I found it eventually, and it does work.

The tester for $0.8 was delivered on time in a consolidated package. And it really works. The brake fluid in the car's reservoir showed up to 2% water content, while the bottle I bought for refilling showed up to 1%. In water, it showed more than 4%, so for that price, you can have the device in your garage.

The product reacts well to the presence of water in the tested liquid. The usage is simple.

This pen is simply excellent, it really does what it says. Just insert a battery, press the button to charge it, and place the tip in the oil; it will let you know if it's good or needs to be replaced. Very good.

It arrived in good condition and quickly, works well, I've already tested it.

Excellent product, I didn't expect it for the price; it's great for checking the condition of the brake fluid.

Received on time. Looks good, the weight shows that it's made of iron. Works perfectly. Everything is fine.

Works very well. Simple test in water, hazard signal triggered, test in brake fluid with an OK result.

It safely arrived, everything seems good and as described.

I haven't tested it yet. If i got any problems, i will write additional feedback, otherwise it is good! In water it does light up all, in my break fluid only the on lights up (no percentage, is it less than 1%? ), but i hope it means it is good break fluid. I will test over time.

I recommend seller and product. Thanks!

Works perfectly. Tested against a more expensive named brand one. Gave the same result.

Product made very well, I haven't tried it yet. The package arrived in Italy in a very short time along with another item. Excellent seller!
