    I ordered the Optimate lithium charger from the Anti gravity battery website. The charger was deliver very quickly but, upon opening the package, I found that the permanent ringlet attachment was missing from the sealed factory package. I the phoned the company and told them of the issue and they sent me the missing accessory. I received it in two days! I appreciate the great products and customer service I got. Thanks!
