JOYTUTUS Large Stable Cup Holder Expander for YETI, Hydro Flask, Hold 18-40 oz Bottles and Mugs, Car Cup Holder Adapter with Adjustable Rubber Base

This product is great Holds my large bottom drink container as I wanted it to.

I had tried another cup holder expander and it was a disaster. While it said it would hold a 40 oz. container (like my ThermoFlask), the holder itself was wider at the top and narrowed as it went down, so that my bottle would only go down partway, was hard to pull out, and was unstable as well! Awful! This design, by contrast, rests in the cupholder of my 2011 Honda CRV very well. The instructions and some of the reviews say to take out some of the rubber tabs for larger bottles, but that has not been necessary for mine. It holds my bottle well and doesn’t stick up too high. And the base is much more secure than I would have expected. Don’t waste money on a more complicated design when this one works so well! Also, I appreciate the clear listing on the Amazon product page that tells you what cars it won’t work with - more manufacturer’s should follow their example! A great purchase and I am very satisfied!

This cup is well built, just too big for my compact car

I love it. Fits perfectly giving me added option for an oversized mug with a touch of bling. Goes beautifully in my new Cadillac XT5.

It's a bit bulky but fits tightly into the cup holder base. Also a bit tight with the shifter. But does what it suppose to do.

I have a 32 oz wide mouth Hydro Flask that fits in this thing nicely. But:-The rubber grips around the rim have come out, thankfully they’re easy to put back in.-The grip in the bottom of the cup is easily removed.-One push and the whole thing is launched out of my cup holder.-I go to take my bottle out of it and it is somehow stuck to the bottle and comes out of the car’s cupholder.Maybe my car just has weirdly large cupholders? Not sure. But this thing would be great if the bottom that goes into the car cup holder was adjustable or something.

My partner loves her coffee. She loves it so much that she uses a 32 oz travel mug every morning. My 2013 Nissan Xterra has recessed cup holders so it would never fit. At least not until I picked up this cup holder.The cup holder comes assembled and all you need to do is push the holder into the existing holder. There are rubber rings on the base and they will grip the sides which holds it in place. There are four rubber fins at the top of the holder which will help keep smaller bottles/cups in place. If you are using a really large bottle, you can remove these fins for the extra room. There is also a slot on the side should your bottle/cup have a handle. Just line up the handle and the cup will stay in place and not spin side to side.At the bottom of the inside there is a rubber 'coaster". If you remove the coaster there is a small empty space at the bottom. You can use this to store change to help weigh it down to stay in place or even put something that you don't want anyone to find in there. Once the coaster is back in place, you can't tell that there is a space underneath.If you drive and carry a larger travel mug or water bottle, this is a great solution to keep it in place.

Great item
