Review on 🚗 NSTART Universal Car Cup Holder Expander Adapter - 2 in 1 Dual Cup Mount Extender Organizer for Vehicles with 360°Rotating Adjustable Base - Holds Most 17oz to 20oz Coffee Drinks Bottles by Billy Dotie

Used for a few weeks on short and long trips. The base, which fits into the main cup holder, slightly covers the edge of the second cup holder, which then creates a small latch where the cups stick together. The rotating cup holder is a great idea, but it doesn't really work the way I was hoping. Large cups tend to be too heavy and will most likely tip over if you brake hard or corner too fast. The small pieces of foam included in the kit to prevent the insert from coming loose too easily are actually not "sticky" enough. The very slight curve in my OEM cup holder still requires me to constantly push the insert down and into the OEM cup holder. 3 extended levers are not held very securely. They don't latch, just little indentations that you feel when you pull them out. I bought a very large cup holder that doesn't fit in my stock cup holder. Because of these issues, I had to return the item. It wasn't right for my car.
