I've been stewing about this for awhile now. As with any stew, the longer it cooks the crazier it gets. Here's what I want:
Flip top lid for Surge/Grow!/Metabolic Drive bottles - and put some kind of rubber gasket in there so when it flips closed it seals right.
A counter top rack for Surge/Grow!/Metabolic Drive bottles. I've got four on my counter all standing upright for various members of the family. If we had a rack that held them at an angle in a vertical stack then they would take up less space and make it easier to make shakes quickly. See also: flip top lid!
Since anyone in their right mind has a nalgene or similar sized bottle, how about a dinky little plastic funnel that fits into a nalgene bottle on one end, and is big enough for a surge scoop (and therefore Metabolic Drive/Grow! scoops) on the other end? How tough would that be?
I'll pay through the nose for this stuff. Who's in charge of non-edible merch, anyway? The world doesn't need anymore #$%& tee-shirts.
