Rovtop Car Cup Holder Extender with Phone Holder, 2 in 1 Big Cup Organizer with Adjustable Base, Cup Holder Adapter Compatible with Hydro Flask, Yeti, 3.4”-4.1” / 20-40oz Cups

Works great! I don’t have a Stanley cup but I have off brands that don’t fit in standard cup holder. Fit perfect in this though! Phone holder is added bonus! I would purchase again.

I like it being all in one to hold the cell phone and cup or water bottle.It is is a bit large, so depending on how you position it, it could partially cover another cup holder.

The media could not be loaded.  Un bonito producto de plástico robusto, fácil de instalar y viene como en la imagen.

Se ajusto perfecto al espacio sumamente reducido para bebidas en el centro de mi auto virtus 2023. Se sujeta bien gracias al sistema para que tiene para apretar la base. Lastima que solo pueda colocar uno.

This cup holder upgrade is pretty solid. To my surprise it came with a screwdriver to assemble it! It allows you to slightly offset the cupholder by about a half inch. The cup holder itself is large. I can fit my Yeti Rambler 769mL / 26oz in it comfortably. The tabs keep the rambler secure and prevents it from rattling around the holder. The phone mount is also large enough to hold my iPhone 14 pro max with the card holder on the back with some wiggle room also. There is some foam around the mouth of the phone holder to protect your device from any damage. There is a small piece for the bottom of the phone holder that is loose and a little annoying to set in place. I would suggest using some kind of double sided tape and secure it yourself to prevent it from flipping and causing a nuisance. All and all it's a great upgrade to hold larger drinks and a spot for your device. Ergonomically it isn't a great solution for my vehicle as its manual transmission and the cup holders are right in line with the gear shifter. I would say for any automatic vehicle and any stick shifts that have an offset cup holder closer to the passenger side would allow this product to work for most people.

This is a handy solution to a problem many of us have - oversized cups and water bottles that don't fit in your car cupholders!It works well for the most part, but for my 14oz Yeti mug (that it specifically says in the manual is compatible), it's a bit too snug. The rubber flaps make it *really* tight so more than once the entire cupholder came with my cup when I went to take a drink! Even when I thought it was tightly installed. So I've had to remove the rubber to accommodate. Which is a bit of a pain if I switch to another water bottle or something.The cupholder fits fairly tight into your car's cupholder, but the same system that makes it easy to install/tighten (turning the upper part of the unit clockwise to expand the "grabbers") makes it so that if you accidentally turn it a little counterclockwise, it will loosen just enough that it can pop out if you pull on your mug/bottle. I found that pulling my mug forwards and up seems to work the best. But I do wish there was some kind of locking mechanism - with a button or something to disengage - to prevent the upper part of the unit from turning and loosening inadvertently.Otherwise, this is a handy device that can also accommodate your phone if you wish, and that part is removable if you don't want to use it. It does stick out a bit and makes the already large unit even bigger. But still can be handy if you're without a place to put your or your passenger's phone.I do really appreciate the offset feature to move it over a bit away from your shifter if it is on the center console as mine is. It comes with a little screwdriver to help you quickly move the screw to offset it to two different directions. You have to determine this after you've test fit it.So overall I would recommend this, though a locking mechanism would make this pretty much perfect. There may be another unit out there with a feature like that, I'm not sure. But overall this is a good solution to one of life's little inconveniences!

I wanted so bad to use this but it didn't fit my car. It is HUGE first of all, I mean probably great for a truck or large SUV, not sure but I don't quite understand what type of car it will fit. Most cup holders now are quite deep. In order to use this, you need an extremely shallow cup holder in order for the base to fit. Other than that, it is put together relatively easy and I love the space for the phone as well. Any cup will fit in snug here and so no worries about spilling anything over or knocking it over. I wanted to love it but had to give it away as it simply didn't fit my car. The base is about over 4 inches long so check the depth of your cup holder before ordering this.
