Great for large bottles in golf cart at course
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.

Worth the Money
These adjustable cup holders work perfectly in my 2025 Toyota Corolla Cross Hybrid XSE. The base is adjustable to fit within the cup holder and the top adjusts to fit both slender and large tumblers. It holds the drink securely. I definitively recommend! It's a quality product worth the money.

Great for the larger cups that don't fit in typical cup holder.
Car cupholders were always too small. This goes easily into cup holder with adjustable snug fit for stability and its quality material that you don't have to worry about breaking. Large enough for even the biggest cups. Easily install and removable.

Not Perfect, But It Helps
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.

Great Value for the Money
Works well and does hold my oversized water bottle securely in my golf cart. A bit bulky but is easy to use and secure.

Sturdy & Will definitely fit any cup holder
The cup holder is super sturdy and easily adjustable for your cup and your main car cup holder. I’m definitely going to need to order a second one. This holds my 36oz YETI rambler well.

Works well, thoughtful design
So far this has served the purpose! I appreciate that the bottom has legs that expand to fit my cup holder and that the top expands to hold my jumbo water bottle. I have no complaints and have had it for 2 or 3 months. Works well.
