Works great, and for a good price relative to others. Takes just a little practice to get it full by squeezing the bulb--no big deal. Highly recommend.

I bought this to check the coolant in my marine engine, where leaks could have diluted the coolant and negated its protective effect. Easy to use: pump a little coolant using the attached hand-pump, and read off the level of protection based on the density of the coolant. Reliable, simple, no electronics needed, and reusable. Really a neat tool to have in colder climates, and when you don't know if your coolant was ever diluted with water.
