Amazon Basics Car Cup Holder Expander with Adjustable Base, Fits Large Bottles 3.4 to 3.8 in Diameter, Securely Holds Yeti, Hydro Flask and More, Black

Works so well for my 40 oz corcicle. I had bought a different one first that was more shallow and wider (works great for a regular coffee cup though so I'm keeping that one too.) and didn't hold my large corcicle securely at all. This one adapts your cup holder spot in your car to be able to hold the larger bottles/corcicle very securely. Great purchase. Easy to put into the car holder and tighten to the right width.

I’m so excited to find a cup holder that fits my NutriBullet smoothie cup so it won’t pop out in the middle of my morning commute and roll around on the floor while I’m driving. It has an adjustable bottom section that fits my new car’s cup holders perfectly!

There is nothing inside the base of the cup holder if there is something cold, water will be running all over inside, that is why I gave it a 4 start

Love this!! Makes it easy to finally get large cups next to me while driving. Also fits smaller cups as well.

Excellent for keeping my water bottle upright. However not functional for drive thru paper cups - lids pull off when try to grasp while driving. Yikes

Unfortunately, I started to use this after the return window closed as I was away. But to warn future purchasers that this cupholder does not stay put and is basically useless, I felt the need to submit my review anyway.

Igual al ilustrado, buena calidad, material resistente, se observa agradable compatible con el interior del vehiculo.

Works great, no problems!
