Good way to free up cup holder
on October 3, 2026

[This review was collected as part of a promotion.] I’m really enjoying having my cup holder free to actually put drinks in them. Lol. It holds your phone nicely so it’s not taking up space in one of the 2. And you can have even a large water bottle in this one. Great addition to car storage.

Great

[This review was collected as part of a promotion.] I really like this adjustable cupholder because it gives me extra space for either extra drinks or even things like my phone or sunglasses. Love that it has an extra large cup holder or cups with a handle specifically such as my Stanley. It is a little finicky, so you need to make sure it fits your cupholders, but I haven’t had much issues with it. Very lightweight and easy to use.

Adjustable base
on September 13, 2026
Posted by: AMBERE
[This review was collected as part of a promotion.] The adjustable base is pretty short so it sits near the top of my vehicle's existing cup holder. It feels secure so I guess it's fine, but they just make it a bit taller and it would seem more practical. The optional side holder is pretty small. Some phones fit, some didn't so if that's what you planned to use it for, it might or might not work. I did find it handy for glasses, though! I will use this for some bigger cups that are wobbly or don't fit the standard holder.

Good for large cups
on September 2, 2026
Posted by: JennyF
[This review was collected as part of a promotion.] What I appreciate most about this dual cup holder is its ability to fit large (40oz) tumblers. It securely holds cups without tipping or spilling. It did not fit well in one of my vehicles (bmw), but easily fit in my truck. It is useful if you need an additional cup holder in your vehicle, but for me, it was a slight inconvenience because it was bulky for my cupholder area.
