Great Price
While the price was the best I could fine online, weeks later I still did not have the battery. After an unanswered email, I called and was immediately told that the company had fouled my order up and that they were wrong and would get the battery shipped ASAP. I liked the honesty, something you don’t see much these days. The shipping details arrived couple of days later and I received the battery the following week. Unfortunately, I was not planning on a month to get the battery, but I would go to these folks again for their honesty in making a mistake and hope it was an isolated incident.
