This refractometer has been a handy tool for checking various automotive fluids. It’s simple to use, and the readings are clear and easy to interpret. I’ve mainly used it for testing coolant and AdBlue levels, and it’s given accurate results every time.What I like most is its versatility—it works for battery acid and windshield washer fluid as well, so it’s a great all-rounder for car maintenance. The build quality feels solid, and the kit comes with everything needed, including a pipette and cleaning cloth. It’s much more reliable than guessing or using basic testers, and it’s saved me from potential issues by catching problems early.
