The battery is ok , not as good as the original nikon so I will not order it agin. However, I think the ad was carefully designed to give their impression that you will get 2 batteries rather one. I said to give you the impression rather wrong ad. It was listed as a Pack showing 2 batteries. I know I can return it and get refund but when you are so busy sometime you let it go.
This is the best rack back I have ever had. Everything bit of it speakers quality. Very clever design in deed, lots and lots of useful pockets and space. It can hold a lot of your stuff including a 17 inch laptop. The thickness of the back can be reduced by simply flipping the baseboard up. It can stand on the floor with no problem. I really like this bag and recommend It to anybody.
