Do not buy!! Problems right out of the box

I just received my battery grip today and right out of the box I thought it was going to be amazing. Once inserting brand new batteries (also arrived today) The grip started giving me problems and not Turning on. I got a message saying a canon battery must be placed on the left side ,so I did as prompted, and then received another message saying grip does not work with counterfeit batteries. May I add, these batteries were also bought from amazon so I don’t think these batteries would be counterfeit.
