Negative Positive
Title: It took two..
Review: I bought one and being dumb I forgot to test it before I put it on. Then my truck ran like crap though so I pulled it out and tested it. Low and behold the thing was dead as a doornail. Thankfully the one to replace that one didn't have a problem like that and I guess it could have happened to any store really..but it was kind of an inconvenience that the first one didn't work, so thats why only 4 stars.
Is the review positive or negative?
