Seven Sparta Car Cup Holder Expander with Adjustable Base, Compatible with Hydro Flasks 32/40 Ounce, Compatible with Yeti Ramblers 20/26/30 Ounce, Other Bottles in 3.4"-3.8" (Black)

This is the best cup holder expander that I have tried so far. I got the medium size with the "basic expander", and it effortlessly holds my 32-oz Klean Kanteen without any wobble. The extendable base adjusts easily to fit snugly in my car's cup holder, and installation was a breeze—just a quick twist to secure it in place. I also like its top rubber flanges that prevent rattling on bumpy roads. It feels sturdy, and it's absolutely worth the investment.

High quality. Fits and holds perfectly.

If you use a larger water bottle and it won't fit in your car's cup holder, this cup holder is for you. It twists down into the car's cupholder until it sort of locks in place, and securely holds my larger Hydro Flask (32 oz). It's a simple design and quite effective - no more water bottles rolling around on the passenger car seat because they won't fit in the cupholder! One downside is this device takes up some of the room of the 2nd cupholder, so you cannot use 2 of these at the same time. Good news is that a regular size water bottle/hydro flask can still fit in the 2nd cupholder when this Seven Sparta Expander is installed. It twists out easily when you want to remove it. Happy we found this so we can stay hydrated!

This cup holder is exactly what I’ve been looking for. It was extremely easy to install, and it holds everything from my coffee cup to my giant hydroflask.

I've got nothing but great things to say about this. It fits my large water bottles. Snugly. And even the water bottles that are skinny that would fit in the main cup holder, fit fine in this too. The whole thing fits tight in the regular cup holder so it's not wiggling around. And I still can put something else in the second cup holder. I haven't tried cleaning it because all I put in it is water. I can't imagine anybody having something negative to say about it!

I bought the two pack so my husband and I could both have one in our cars. They are very high quality and I love how you can turn them to tighten them in the cup holder. They are perfect for our yeti and simple modern water bottles.

Wide holder but not tall enough for larger heavy bottles. It's not the most efficient for tall heavy water tumblers. The inside is not adjustable so some tumblers wiggle and don't stay secure. The bottle adjusts to fit in the car drink holder, but does not for the water bottle. This is not made for all sizes. It seems to be able to fit the larger bottles. However the design to hold the bottle in is not very tall for heavy bottles. This model did not fit my 40 OZ tumbler. The tumbler was wiggling way to much to hold it securely.

Bought these for our flasks - use in my 2023 Ram 1500 Laramie and they work great. They are super easy to install and have held up well. Been using them now for quite some time and have no issues with them.

Very sturdy, and fits all of our drink holders!

Llego en perfecto estado , cumple con lo que promete.

Very sturdy, holds the flask well, but quite big - may not fit in some spaces.
