I’ve finally found a cup holder expander that works in my 2012 Prius 3!!! While I love my Prius the one downside has always been that the cup holders are weird and a 40 oz water bottle doesn’t fit. I found it on Amazon for $29.99, under the name “Swigzy Car Cup Holder Expander Adapter (Long Base)”. This is the first and only expander in 3 years of searching that fits both the cup holder in the car AND a 40 oz hydroflask.
