Negative Positive
Title: Total junk
Review: Don't be surprised if your belt snaps on you while you're trying to tension it to the spec using this junk. This tester consistently reads values that are like 1/2 what the actual tension is. Perhaps it works on that one exact belt they used to calibrate it, but I couldn't care less because it is not the belt my car uses. Too bad there is no 0-star rating, as this is exactly what this product earns. The price under $20 for a working tension gauge sounds too good to be true? Then it probably is.
Is the review positive or negative?
