I Like It

Honstley it works pretty well its just the material i thought would be better but i mean its for the cup but it works well i love it whenever i wanna have my electrolytes i use it on one side and my cold water on the other side

Perfect for Gym

I’m usually not one for ‘trendy’ gear, but this thing is actually solid. I can keep my pre-workout or protein on one side and ice water on the other. It saves me from dragging two shakers to the gym and fits right in the truck cup holder. Huge win.

Love it

I didn’t think I’d like it at first, but I was wrong. Having my water and my iced coffee together is the daily upgrade I didn’t know I needed. Obsessed

Very Useful!

I was skeptical when my daughter asked for this, but it’s been the best purchase. It actually fits in the cup holder while holding two drinks!
