They are not selling authentic macpro chargers. They show a picture of a mac charger, they say they sell original chargers that come in the original packing and that they are an authorized mac dealer. This is all a lie. The battery is about 40 percent larger than my original, is multicolored meaning has different whites showing the pieces they used to put it together and is certainly not original. They will let you return within 14 days but you have to pay for shipping and handling. They are a fraudulent company that is guilty of scamming people. They charge more than other companies that sell rebuilt or replacement mac stuff, so I was dumb and thought I was getting an actual Mac product.
