I have a 2010 BMW, which I love, but my biggest complaint has always been the tine little slide-out cup holders. I've had the car for 6 years, and I wish I'd bought this product on day one! It is awesome. You must buy one now! It fits my soda stream bottle, and the bottom part locks into the cup holder so it won't come out. I would give it 10 stars if I could!

I love the genius of this cup holder! I have gone along time with my normal cup holder and frustrations with bringing my large water bottle on long drives with nowhere to put it, usually ending up rolling on the floor . This is easy to stick in the cup holder and twist until nice and tight . Holds the water bottle really well. And easy to remove as well .

We have an RV with a shallow cup colder and smaller size cups wobble in it. This great cup holder seats firmly and securely in the shallow cup holder, and can accommodate any size cup or mug - yes mug with a handle!! The rubber flaps at the inner edge hold even the smaller cups or cans in place. A real quality item. Received it today and am buying another now. Sadly, its $1 more than 2 days ago. Great item but a bit pricey.

Highly recommend this cup holder for the Hydro Flask and other larger Hydration bottles. The mounting sits tight in the cup holder. I have it in a 2001 Rav 4, 2006 Corolla and 2001 Silverado. I have used the press in holders and these are much more secure. I have a skin on my 40 oz Hydro Flask, so it is a snug fit but it still goes in. The rubber fingers do a good job of holding smaller bottles or cups. More money than a slip in, but it will not come out with your Hydration bottle ....... very secure and recommended

Very sturdy and well thought out cup holder. We have a 40oz water bottle that doesn't fit into car cup holders and this works wonders. Also works with our other water bottle holders too. It can be locked into a cup holder by twisting.

Bought this to fit my cup holder in my lexus 2006. My mug is too big to fit in it. Works just like said and now my cup is stable all the time.

Works great with 40 oz Hydro Flask container. Adjusted easily to cup holder in my 2019 Honda Odyssey. Container fits perfectly. Easy to put in and remove.

My 32 oz water bottle has been rolling around on my passenger-side seat or floor...until now! Great invention and product!

This is the greatest invention ever. I drive a 1998 vehicle daily and will for the rest of my life. Back in 1998 we had soda cans and soda can size cupholders. In today's world we have BIG GULPS and giant coffee cups. This clever device converts tiny to BIG in the matter of seconds. It holds everything I put in it securely and I don't lose a hand to holding a soda. If you suffer from inadequate cup holder this device is the answer. Trust me.

Chyuhh! This cup holder-expander is excellent!! I was pleasantly surprised with the materials - very sturdy. Also, it. does. not. rattle! For those of you who can’t get enough of the larger Hydro Flask/Yeti’s and are tired of them flying off of your passenger seat onto the floorboard, praise be it this little guy. I was waiting for a hot minute for this to come back in stock. Do yourself a favor and just shell out -/+$20. So here’s the compatibility breakdown (mind you, this is not all inclusive, just validation for my gear): Hydro Flask 32oz Hydro Flask 40oz Yeti Rambler 26oz Yeti Rambler 30oz Camelbak Chute Mag 32oz Camelbak Chute Mag 40oz (it’s tight, but fits) S’well Traveler: 16 & 20oz Nalgene bottle: 32oz Cheers!
