Car Cup Holder Expander, Cup Holder Extender for Car with Adjustable Base, Fits Yeti 24/36/46oz, Hydroflask 32/40oz, Large Bottles in 3"-3.9" (16-40oz)

Ingenious! Well designed. A+ for the day.Interestingly no instructions! So you’re sitting there wondering how T F this thing adjusts to varying size cup holders. Seems like there’s absolutely nothing to adjust. Ok so seeing that there is only one thing that you eventually figure out - will rotate. You rotate it and these evenly spaced square bars extend out from seemingly flat round surface. Voila ! You just insert & rotate until tight.That was easyReally … couldn’t include one simple little piece of paper pointing to base saying “rotate”Also using the old tinker tanker a bit you see you can “offset” the cup holder part so wonderfully in my case where existing dysfunctional holder is very close to shifter it gets it ( the coffeee cup) away from shifter.Holder itself is also well designed. IMHO holds all widths all Dunkin liquid delights.Unit can be removed / installed easily. No need to buy more than one.Seems very well made.

I have a Yeti cup that is unfortunately, 1/8” larger than the 3-1/4” dia cup holders in my 2017 Nissan Maxima. The cupholder can be assembled so it’s offset from the centerline of the car’s cupholder but in my case, assembly with it all centered was perfect.It is terrible when there is no safe, secure and stable place to hold your hot coffee while driving.This cup holder is reasonably priced, a perfect fit and does the job. The cupholder holder is adjustable but just double check the diameter of your car’s cup holder is not too small

Works well for my 24 oz tumbler that has a rubber bottom added on it. And there’s still room for an another drink next to it. Easy to install. Feels like it will last a long time and drink will be stay stable.

I would give it 5 stars if it didn't keep gradually loosening itself over time and get inadvertently pulled out with the bottle on occasion. Other than that, it definitely serves it purpose and fits my 32 ounce water bottle perfectly.

Works really well to hold my big ass Stanley in a cup holder, so it’s not rolling all over my car. Even holds huge Nalgene water bottles too

I have several large water bottles that always leak sloshing around on the floor of my car, this was the perfect solution. My large water bottles now fit in my cup holder and I’m so satisfied with this purchase

Why vehicle manufactures can't make larger cup holders is a mind bender. Bought this for my Owala 32oz, and while initially it seemed to work fine, after a while the whole system seemed to loosen up and wouldn't tighten back up. So every time I pulled out my water bottle this big honking thing came with it. Finally stopped messing with it and gave up. Now my bottle just rolls around on the seat all sad and haphazardly.

Much larger than expected. This is meant for the large bottles, not for large cups. Turns out the 50oz cup I got fit in my normal cup holders just fine. This DOES hold my 64oz metal water jug very nicely though. It's pretty easy to use, and works in the cup holder tray I got for the floorboard in my pickup with bench seats. I'm happy with it, but be aware this is not for cups.
