Integral Ultimate Expander Car Cup Holder - Adjustable Base - Expander & Organizer for Vehicles - Compatible with Coffee Mug, Yeti 14/24/36/46oz, Ramblers, Hydro Flasks 32/40oz, 3.4"-4.0" Bottles

The ONLY height adjustable and small enough base diameter (2.5 inches) to fit in my car. All the other products cant be height adjusted so cant be used in awkward places. Thank god for this company, if you're reading this thank you very much for designing this item properly with the user in mind. Youve made every work shift of mine more bearable.

Wasn't sure what to expect - turned out to be great. Expanded to fit snugly into my original cup holder and firmly holds my 40 oz thermoflask in place while I'm driving. Bonus is I can still use my second cupholder for additional beverages. Easy to remove when not in use. I can't speak to durability as I've only had it a few days. I bought a second one for my daughter.

Does it's job, but this is overpriced

My first Christmas gift opened and the holder works and fits amazing in my 2015 Honda CR-V. It is very easy to adjust the depth adding spacers with one screw and adjusting the base width/diameter to fit snug in the tiny front council cup holders.

Very happy. Fits my Yeti 46oz Rambler perfectly. Fits in my truck. So happy my water bottle doesn’t roll around everywhere. Thank you!

Very sturdy. I used the height that came installed. It makes it so much easier to reach without looking or struggle removing and placing a cup in the cup holder. I drive a bumpy dirt road and the yeti hasn’t fallen out. I drive a 2025 Ford F150 and it fits well. I haven’t tried the offset position , but I like the option .
