DYLENCar Cup Holder Expander, Cup Holder Extender Adapter for Car with Expandable Base, Fits Yeti 20/26/30/46oz, Hydroflask 32/40oz, Large Water Bottles in 2.8"-4.2" (16-46oz)

I’m a school bus driver and get various cups as gifts from my kiddos and this was an amazing cup holder. Love the tightness of the adjustable bottom and putting my phone on the side keeps it from falling on the floor. It’s also nice because it lets the cup sit higher for me and deep enough that the taller cups stay put… no top heavy falling.

I bought it to be able to fit large tubler. Works perfect. Good value. Good quality. Easy to install. I love the offset which allows room to use both cup holders in the car. The phone caddy is a nice feature (and is easily removed if I don’t want to use it).

Fits great in the cup holder, so it was easy to install, has a place for my phone so quality built that works great. It's stable when the water bottle is in it .

This was really easy to put together and twist into my cup holder! I love how it fits my big water bottle and my phone! 10/10 👍

I have needed this for some time to store my 32oz water bottle. I don't know if I will use the phone holder or not. But I love the screw out base that secures it into the vehicle's cup holder. Once in place, it's not going anywhere. The phone pictured is a Samsung S8+ with an Otterbox Defender cover on it (measure 3 5/16th inches). It fits nicely but not much room remains. Anything measuring 3.5 inches is pushing the limit for the phone holder. I would buy this product again.

Works great for very large cups. My yeti tumbler that is too large for the regular cup holder bangs around in this one due to the plastic holder pieces being flimsy. Needs stiffer plastic pieces.

The cup holders in my 2008 Pontiac Vibe barely fit anything, especially the smaller one so I got this to fix that problem. It fits perfectly, especially since it has the option to offset it. Holds my Owala pretty securely. The rubber pieces inside aren’t super stiff so my thin water bottle does wiggle back and forth a bit when turning, but it never falls out and always stands back up. The phone holder is great, it even fits my boyfriend’s big ol iPhone 14 really well. The hole for the charging cord is great too. I love this product, it definitely saved me the trouble of having water bottles rolling around all the time. Definitely worth the price.

It's good for golf cart, but I will say it doesn't fit the tall Stanley cups as well as expected. My cup is taller and the handle from the cup is taller than this plastic holder. It will hold it, but not snug enough for more than flat surfaces. They could have designed this just a little bit better.
