Great to filler up quick in situations were time is everything. I cut mine down some and took a length of the hose I had cut off on my ice plate to make it fit to my mouth better. Put the hose in the funnel so now I have a collapsible funnel that doesn’t take up as much room.
My son had recommended this in conjunction ob purchasing the ice pack unit and boy, am I glad he did! It is very well constructed and a handy little addition in fill the ice pack.
