Made the appointment on line and selected the battery for my MB CLA250. I was told the installer would be at my home before noon and would be coming from Milwaukee as a Chicago based employee was on vacation. After a number of calls the technician arrived at 7:30 pm with not the battery type I selected on line but with one that was not suitable for my car. The technician bought the correct one locally and installed it. The technician was a very nice man and I felt sorry for him. 188 battery promised the battery would be installed that da and it was. That is why I gave them 4 stars. Stuff happens no point in getting upset and I did have things to do around the house.
