Hi Jerry. I am confused by your feedback. Our starters all come with a warranty, so your new starter from us would have been covered. What car were you putting it in? What is the name of the shop that installed it for you? You state it is a certified mechanic. I would be happy to speak to the mechanic directly about it. Did the starter just start to smoke upon install? Did it make any noises? What were the symptoms? Please contact is directly for resolution. We guarantee all of our starters, and I wonder why we never received a call or email from you? I find this negative post suspect because I was never contacted about the starter going bad. And because all of our starters have a warranty, a real customer would have reached out to us for advice, a replacement starter, or a refund. In my 5yrs of running this company, this is a first. That one star rating should be taken with a grain of salt.
