Drink Dinghy - Hands Free Floating Drink Holder -- Lakes, Pools, and Rivers (Pink, Single Drink Dinghy)

The donut part is a durable foam material and the insert cup is plastic. The insert must be removed to fit / wedge in / hold a 30oz Yeti tumbler. It can't be completely full, otherwise it will flip over easily, so sip your drink down and inch or two before you put it into the float. Plan on picking up the whole thing for a sip instead of taking it out and putting it back in the float again. Got a cool silicone straw to make sipping less drippy...The bungee wrist tether is pretty neat, and makes it easy to keep your drink close. We used the clip to tie it to our hammock float instead of using the wrist bungee, but either would work great.The plastic up part...I wish it was just a simple cup without the graduated / tiered bottom. Using my 20oz Yeti or tumbler of that size, the bottom of the cup holder is a problem. It tips other tumblers to the side, because they can't sit flush with the bottom of the cupholder. It's made to snugly hold a can at the bottom-most part of the cupholder. In reality, few would want to can straight into the cupholder without a koozie around it. This design is more trouble than it's worth. If I were to redesign it, a simple, single-level plastic cupholder would be better, with a counterweight at the bottom for stability of the overall float. I'm getting a couple stone car coasters to put down in that part of the cupholder to help solve these issues.Overall, I did a lot of looking, and this is the best float I've seen for your stainless tumblers, and the best tether setup, too. Can't wait to take it on a resort trip here in a few weeks!

I used this in a lake. It floats really well. It holds a regular size solo cup perfectly with the center plastic piece in it. We removed the plastic center piece and used it to hold a 30 oz Yeti tumbler. It fit perfectly also. The lake was pretty rough, and it did not need to be supported to keep the drink upright. I will be ordering more for other family members for the next lake vacation.

Love love love my drink dingy! It’s perfect in the lake or pool! It’s my favorite new lake accessory!

We no longer use it as its not stable at all

A little large for my liking

The dinghy flips over very easily with a drink in it.

This product is awesome! I float my 30 oz RTIC tumbler in it perfectly! Of course you have to remove the cup holder first! It handles up to 3 foot rolling waves with no problem. Best product out there for floating your beverage!

Works perfectly. We habe a dozen of these on our boat and use the all the time with the big Yeti Tumblers and just have to remove the insert for them to work great!
