Very quick service but there were a couple of disappointing issues. 1, the Diehard car battery which I thought purchased, ended up being a different battery, I was told it was equal to the original. Called 800 # to complain and was told in the very fine print which was not easy to find, that they reserved the right to replace with similar battery, just wish that information was more upfront. Also they said that the technician would test old battery to make sure it was dead and not just in need of a recharge. My technician did not have the equipment so never really knew the exact facts of my old battery. Was also told someone would contact me about issues for possible discount, never received any communication. For these reasons I will definitely look elsewhere when needing to replace my car battery, disappointing experience.
