I wasn't sure about spending 10 for a cup holder, but I am very happy I did. I was concerned that it would make the carseat too wide. The back seat of my Mercedes GLK350 has bolsters on either side of the seat and every booster I tried was too wide. I am happy with the fit of the Oobr and the cup holder fits perfectly!

Extremely easy to use and a must have for the seat.

Nice cup holder does what it is supposed to. I like how these cupholders are removable and can be taken out if you need the extra space.

Easy to install and easy in use .

My son loves his booster, but kept wanting to reach to get a drink while in the seat. He's used to carseats having cup holders. This solves the problem. He stays in his seat as intended and can reach his drink.

I love how this cup holder locks in so my daughter can’t pull it off. This is the best cup holder I’ve seen on any car seat I’ve owned.

We love this cup holder! Even though our seat came with one we decided to add a second to hold additional items.

This cup holder is of good depth and diameter, such that for most 12-16 oz cups, young kid could easily take cup out and put back in, yet the cups are stable to sit in even at panic brake.Sometime it interferes when buckling seat belts with oobr.

Great addition to your clek seat! Deep enough so tall cups aren't easily knocked over too!

I don't like to have bottles in the car all the time, but when I do it's because my child needs hydration. The drink thingy came with a wonderful surprise design inside the cup. Cute!

We bought this for my daughter since she has been jealous that my son's booster seat came with a cupholder. It sticks out a little, which is kind of a pain, but it was easy to install and works well. It is definitely nice to have a cupholder for longer trips.

bought double. the booster already include this cup
