Car Cup Holder Expander, Cup Holder Extender Adapter with Expandable Arm and Adjustable Base, Compatible with Yeti Ramblers 14-64oz, Hydro Flasks 18-64oz Most Coffee Mugs Bottles & Cups

i purchased these to go in the cup holder of the golf cart at the course. We bring 30oz water bottles and they are very sturdy and holds the bottle securely. They are very easy to use, slip in hole and twist it a couple of times and they are tight. They work great and can hold many different sizes of bottles. The top has a sliding button to adjust the bottle size and I have been using these for about a month every week day and have not had any problems with them. I wish they came in different colors so they would stand out in the golf cart and I wouldn't forget to get them out.

A set of these in the backseat armrest accommodates two large jars for the ride home. I like how they adjust to the cup holders and also to the size of the cup, jar or Stanley. Easy to install. Stable. Expands well. Holds heavy jars well. I got a good price, but they’ve gone up considerably in just a little over a month. I wouldn’t have paid today’s high price. It’s just cup holders for pete’s sake. 11.50 a piece is fine. Over 15, absolutely not.

My wife has a favorite water tumbler that is oversized and won’t fit in normal car cup holders. Gave this a try and it works great! It can be dialed bigger or smaller to fit almost any size drink container, and can be adjusted in a second when using a different one. It also has a greater depth to it that keeps drinks more stable in it.

I volunteer once a week at a local hospital driving a golf cart to shuttle patients/visitors from the parking lot to various hospital facilities. It can be HOT here, so I prefer a 40-ounce tumbler for my water. The cup holders in these old golf carts are fine for a disposable water bottle, but too small for my tumbler. Friction fit it a little bit, but hit a bump and it falls out. Sought a solution and found this. It works fairly well. Adjusts two ways - to fit the cup holder, and to fit the container. With vibration and bumps, the settings can loosen up a bit, hence 4 not 5 stars. Periodically check the adjustments and you'll be good.

This works ! Others I had would not adjust to existing truck holder . It would pop loose adjusters would slide into cup handle slots in holder . This one grips and holds tight . Will open really large also . It will hold a really large jug of your favorite beverage . A+++

I got this for my car because I have a thermos that's very wide and wasn't able to fit into my cupholders. Sometimes when I'm hiking or going on trips, I used a larger one because it does fill a lot of water for my drinks and it just does a great job unfortunately is not able to fit in my cupholders and is too big to put it anywhere so this cupholder actually does a really good job with holding it and is super easy and simple to use. I've had no issues with it being sturdy and it is actually nice to be able to put my cup or thermos there and not have to worry about it toppling over or not fitting, which is nice.

These cup holders are very adjustable, both for the auto cup holder and the cup used. The fit for both is very tight and unlikely to fail based on a couple weeks of use in 2 vehicles with different in vehicle cup holders.

Just got these and they were what I was looking for with the adjustable bottom and top. Also a descent value for what they cost. I was a little disappointed that they were a little cheap made & somewhat raggidy. The upper adjustment for the cup snapped and popped when changing the size, I didn't like that. Holds drinks well, but a little flimsy. Stability could be better too. So I would rate the quality low. I wouldn't purchase them again.

Expandable cup holder works well in our Tesla Model 3. Holds everything from a small can of pop to a large water bottle. Snug fit into the existing cup holder and holds larger items securely. Very happy with this purchase.
