Cup Holder Expander for Car, Automotive Drink Cup Holder Adapter with Adjustable Base, Compatible with Coffee Mug, Yeti 20/26/30oz, Ramblers, Hydro Flasks 32/40oz, Other Large Bottles in 3.4"-3.8"

I've had this expandable cup holder from over a year now and it is so durable and well made! We have used it in an RV in the cup holders to expand the size capacity and have since kept it in the van as it works beautifully for larger water bottles! Great product!

If you feel the need to carry around a water bottle large enough to satisfy a camel, this cup holder is perfect. It's a bit bulky and takes up some space, but so does your bottle so... no better match am I right?It hand tightens into the cup holder and holds tight. I check it every now and again and sometimes it gets loose. I drive a truck and I go off road, and no complaints

Putting it in place was a bit odd but not difficult—you place the base in the cup holder and then you turn the top until the base’s bumpers have expanded far enough that the item won’t move around. I use it in my German car with its teeny, tiny shot glass-sized cup holders; the Germans seem to be trying to prove a point about our American excesses when it comes to insidious items like water bottles or smoothie cups. The soft silicone flaps keep your cup securely in place while still allowing for instant removal of your cup. I also put my phone and keys in it a few times and that worked nicely.

I love this. I tried a few other holder, but they were lacking. This one “screws” in to your existing cup holder and gets really snug in there. It fits my coffee mug nicely. Sturdy too.

Excellent. Durable product that does just as advertised. Highly recommend. Installed in my 2023 Tacoma so I had something to hold a larger water bottle or cup.
