Exactly what I needed.
This product is exactly what I was looking for. My first impression was sturdy, with good mechanism and better engineering. I have an unusual situation, where there is a middle separator in a wide oval opening. This product is able to fill the opening and remain stable in the opening, and fit very snuggly. I was very encouraged by its ease of use as well, no problems. Take product out of package screw base to cup, and done! took less than 20 seconds, and I was able to utilize a cupholder in less than 30 seconds. I thoroughly recommend them …buy a few, if you have these unusual situations where you’re forced to HOLD the cup, while it’s in the cupholder to keep from tipping over. If this is you, THIS is what you want to get.

Total game changer for big water bottles
This cup holder expander has been such a great upgrade for my car. My water bottles were always rolling around on the floor or getting lost under the seats. It drove me crazy, especially when I would hear them sliding every time I turned! This fixed that completely. It fits my larger bottles perfectly and holds them steady while I drive. The adjustable insert makes it easy to get a secure fit. I also love the cutout for mug handles because it makes bringing my coffee along so much easier. Now on quick morning drives to drop my son off at school, I can bring my coffee and not worry about it tipping or spilling on me lol! It feels sturdy and doesn’t wobble or shift around. This has been one of those small purchases that makes a life much easier!

High quality but think twice if you're buying it for a yeti mug
Very high quality compared to what my expectations were. Very easy to use just slide it in twist it and conforms to the size of the cup holder. The top section that holds your cup is very deep and would be perfect for large tall drinks. I am giving it 4 stars because Of how my yeti coffee mug fit into the cup holder. The mug fits but because the holder is so tall the tightness of the fit it makes it difficult to remove to mug. How tight is it you might ask, it's so tight that if I rolled my car over it probably would not fall out.

cup holder for car helps!
I like this product absolutely. I dent know if others would be just as good though. They certainly seem so. The mechanism to keep the cup holder in place, works very well. I love the height. I can grab a bottle without looking or guessing where it is because it makes a bottle much higher for easier grabbing. So, yes, i think everyone should get something like this.

Amazing car cup holder
This is the best cup holder ever. I had several water bottles that just didn't fit in my standard car cup holder. Just pop this in and boom, everything fits now. You can offset it which essentially allows for more or less room in your cup holder area. Strong, durable plastic. Even the base is adjustable to fit your car cup area. Super easy to use and set up. Strong suction and the top tabs really hold in your water bottle. Awesome price. So happy I bought this.

Best of the rest
Fits perfectly in my Toyota Cross and holds numerous bottles. After trying two others this one came out on top. Simple to use and stays in place.

Does not stay in my cupholder well
In theory it works and it might work well for some cup holders but in my car it is hard to get it snug and i end up pulling it out when i go to pick up my bottle often

Great buy
Love this for my car. Makes it where I can fit my Stanley bottle. Holds securely and very sturdy. Was easy to install and haven’t had to change it in months.

Great Product!
Great product! Easy to put together and fits my large yeti in which I bought this product for! Glad to now finally have a cup holder for it instead of letting my bottle loosely hang around my car!

Life changing
After purchasing several cheaper versions over a few years I had given up on the prospect of finding anything that would hold our (not that huge) drink bottles. Before a recent roadtrip I decided to splurge a bit more for this and it delivers exactly as promised! Previous styles cannot hold the bottles securely when the vehicle is moving, this fits exactly where you need it, has great grip, no movement at all. Despite the bottles leaving some gaps around the side it still doesn't slide around. It's made a huge difference to a very small first world problem. Will probably buy more for additional car.

Fits my massive Stanley
I have the big Stanley with a side handle and it fits securely in this. You have to make sure the little rubber flaps inside are facing upwards which I've found means I just need to push them up once my cup's in. Before I realised this, the cup wobbled so I should definitely have read the instructions first! The cup bit at the bottom fits in my Renault Kadjar cup holder so I'm very happy.

Top Adapter für den Getränkehalter vom Renault Zoe 135
Meine Frau trinkt im Auto immer aus 1,25l Flaschen eines Brauseherstellers. Die passen nicht in den Getränkehalter der Zoe R135. Mit diesem Adapter klappt es jetzt absolut problemlos. Einfache Montage (1Schraube) und stabile Klemmung. Top!
