A great experience! I ordered total of 10 Crown Deep Cycle batteries. All arrived very promptly, much sooner than I expected. Eddie was very helpful, and followed through on my questions and concerns. I was initially skeptical, but these folks absolutely were 100% solid!
I’d buy from them again, with no reservations.

I am extremely pleased with the work and service your representative Vanessa performed. She was knowledgeable and had great phone presence. You had better promote her before another company offers her a better opportunity. Elizabeth Wellings and Steve Chin, Tenino, Wa.
