Sippy cup

My son is going to be one next week. I’m trying to get him to use a sippy cup but I’m having a hard time. I’ve been trying for months but he’s just not interested. Sometimes he’ll try it. I’ve tried multiple ones and I set them around the room so he can pick one to have or when I feed him I try giving him a different one every time. But he just rather have a bottle. Any suggestions how to get him to use one? Or one you found worked best?
