Review on 🚗 Adjustable Car Dual Cup Holder Expander Adapter with 360° Rotating Base - Hold Up to 17oz-20oz Bottled Coffee, Beverage Bottles - Multifunctional Vehicle-Mounted Cup Stand by Dean Wildfang

Bought to hold my hydroflask, due to the larger shape of the bottle it doesn't fit in my standard car cup holder. And while it's a good idea and generally works, the second holder's rotating mechanism is already showing signs of wear. It's pretty flimsy when the second holder is inside out and the first doesn't support my hydroflask. While this is a cool concept, it actually requires a lot more thought and work. Overall it still works for my intended use but not a very good dueling coaster as advertised.
