Negative Positive
Title: Works, sort of
Review: I bought this because I needed an inexpensive way to balance my mower blades. It does this, but is difficult to use and is not very sensitive. A blade has to be severely out before you can tell on this, and the tool has to be resting on a level surface to be accurate. This tool also pivots both directions (laterally and longitudinally), so it is difficult to tell where the heavy side really is. This is better than nothing, but just.
Is the review positive or negative?
