This thing saved my life...I use larger sized Naglene and Hydroflask water bottles which don't fit in any of the Outback cupholders.
This item is a little pricey, but highly customizable and fits snug. I can also use my full sized tall insulated coffee mug in the second holder while my water rides up front. Highly recommended.
