Bests & Worsts Reviews from Amazon

ACDelco licenses it's name to this product made by Durofix. After tightening two 5/16" bolts to 22 ft lbs, this unit completely separated from its housing at around 16 ft lbs attempting to tighten the third bolt. After speaking to Durofix about warranty service, it was completely apparent they had no interest in objectively looking to see if the product was defective. Gino (the "technician" I spoke with) was insistent that the product was neglected or misused, but said he would take a look at it if I sent the unit back to them. Sure enough a few weeks later I received the unit back with the following letter: "After close evaluation and maintenance of the tool, I have determined, that this tool has been neglected and misused, we warranty all of our tools for one year from the date of purchase, against workmanship and quality of the tool. NEGLECT AND MISUSE IS NOT PART OF OUR WARRANTY COVERAGE!! Thanks Gino" I am not sure how using the tool for one time, within the specified torque range, exactly how it was intended, is either neglect or misuse. But I guess it makes more financial sense to send a letter than replace a faulty product. If you are expecting an ACDelco quality product backed by a reputable warranty, look elsewhere.
