This shaker cup is really nice. It feels good in the hand, and doesn't leak. The unique jax shaped mixer ball, really gets things blended up and disolved.
I picked this up for my sister who is a breast cancer survivor, so I got it in pink. I was really happy with how well it actually worked. I've had other mixer cups that always left things a little chunky. The other thing that caught my eye with this one, was the fact that it has a place for a D ring clip, so you can clip it to your workout pants, or to a bag, etc. Also it being made from materials that are BPA free was another selling point.
They have other colors, but like I said this was for my sister, and she loved it.
