Upgraded Car Cup Holder Expander Adapter with Offset Adjustable Base, Compatible with Yeti 14/24/36/46oz Ramblers, Hydro Flasks 32/40oz, Other Large Bottles Mugs in 3.5"-4.0", 1 Pack

Cup holder works great. I personally found a new use for the seven spartan cup holder. It works great in a golf cart cup holder.

Wow, wow, wow! I almost never write reviews but this product is impressive! I have a 40 ounce Hydroflask bottle (with a bottom rubber cover) that was just impractical to travel with in the car. It kept tipping over. This Seven Sparta cup expander solves that problem. Easy to set up and install. They even went above and beyond and included a nice miniature screw driver. Although I am not currently using it I love they designed it with an offset. The expander fits snug in my car's cup holder. My Hydroflask bottle just works so well with it fully filled with ice and water. Just very pleased over all and highly recommend. Nothing feels cheap about it and I expect it will last me for a very long time. So happy it provided a solution to my dilemma.

Took me a few tries to make sure it was tight enough. It kept coming out whenever I lifted my water bottle, but now it works! You have to keep twisting it to the right until it is locked in tight.

Love this for my truck. I drink a lot of water and my RTIC 40 oz water bottle did not fit in any holder. This expander works perfect! It holds my bottle nicely and is very sturdy in the truck. I have not had anything spill while using it.

Got this as a gift for someone and it works great. Fits in all size cup holders. Very sturdy. Fits all size and types of cups.

So I’ve had this “burrito holder” for a couple of months now, and honestly… it might be the best purchase I’ve made in years. Before this glorious invention, eating a burrito while driving was a full-contact sport. I’d either have to keep holding it—getting my hands all greasy—or set it down and risk a catastrophic burrito blowout all over my truck.But not anymore. This bad boy is built like a tank. It fits snugly in my truck’s stock cup holder and cradles my burrito like it was born for the job. I’ve even gone off-roading with it and still haven’t lost a single burrito.Bonus: When I’m not packing burritos, it holds my massive Yeti cup like a champ. It’s basically the Swiss Army knife of cup holders. 10/10 would recommend—especially if you live life one burrito at a time.

So glad I can finally put my 32 oz Hydroflask in a car holder. No more rolling around the front or back seat!

I bought a pack of two for my boyfriend because he has the larger Yeti water bottle. It was so I could keep one in my car and one in his car. I have a Forrester while he has a F150. It works great in his car, but in my car, it falls out of the cupholder a lot. Be mindful if there is a cupholder divider that is removable because I think it’s more likely for the cupholder accessory to come out.
