Title: Works well, I found it to be worth the $$$.
Review: I bought this after having some problems using a similar, less expensive, single chamber device. My issue was that with the single chamber when the coolant level rose in the radiator the test liquid would become contaminated with coolant, giving a false positive. (Yellow coolant plus blue liquid, gives green color) The two chamber design eliminated this problem for me, also I found the hand pump simpler to use than hooking up a line to the intake manifold or other vacuum source. The instructions are concise and easy to understand. The reusable carry case is a good thing to have. This is tool should be handy for the more accomplished DIY or professional mechanic alike.
