I give it 5 stars!! They came out but we missed one another. However a couple of phonecalls later it was reconfirmed and he returned to insert the new battery. I was visiting so my auto sat outside in some very nippy temperatures for about a week. But when I got ready to leave, it started right up. Drove from Kansas City, MO to Fort Worth/Arlington, TX without a hitch! Took it to my local service mechanic and he gave it thumbs up for the quality of the battery, as well as the hook-up. Thanks for a job well done! I would use them again without hesitation, especially if out ot town!
