Auto Drive Cupholder Expander - Car Cup Holder Adapter for Beverages up to 3.7" Diameter, Plastic

I bought this cup holder to use with my coffee mug. And it works. I like the way the mug handle fits in the slot. Now I can take my coffee in my coffee mug to work with me on my drive into work. I like that. Worth the money for this feature alone.

I have a older model truck w/ cup holders not deep enough to support 40 oz insulted cups without tipping over with each turn, this solved the issue

I bought this for my husband to use in his car. This fits in the cup holder in his truck perfectly. Our coffee mugs are oversized and they fit in the cupholder expander with no issue. Great find for a great price!

This is a handy tool for the car, it helps my cup fit and I don't have to worry about spilling anything.

My car has really awkwardly placed cup holders and this really helped me have an easier time taking in an out drinks.

It is ok. I have a large Yeti mug and it works perfect. Although, For the price I think there are some better options.

Worked for my needs in the side by side cup holder.

it's a good value, it's big enough to hold a large coffee mug, and I like the fact that you can take out the middle divider and make it extra tall for a really large like thermos, it was really easy to install just set right in the cup holder. The things I don't like about it are it's a really cheap plastic and it has no kind of grip on it so if you have something that's significantly smaller than it that would maybe normally fit in your regular cup holder it can move around quite a bit. I mean it's easy enough to just take it out I guess but that's just more of a hassle I've seen some other ones that look like they kind of like expand to the size that you need with some sort of a spring-loaded mechanism but they're also probably at least 150% the price so you get what you pay for but he definitely works can't complain too much

I bought it to hold our 14oz Yeti mugs. It did NOT so I returned them. They also feel ridiculously cheap. Almost remind me a big gulp plastic cup. The kind you use to get at gas stations. The plastic if very thin.

Great quality piece. Sitting cup holder easily however when you add a large cup it becomes too heavy and rolls right out to the floor with the insert.
