Review: Easy Modification -- Prevents holder from tipping with heavy drinks - More than you need or wanted to know about a cup holder. My auto's cup holder inside diameter is 3 5/32 inch. The bottom section of the Gadjits Cup Keeper outside diameter tapers from 2 5/8 to 2 1/2 inch. It fit loose in my cars holder and was top heavy with cups with handles or large drinks. My first thought was to add weight (quikrete?) inside the holders hollow bottom section for stabilization. However a better and easier solution: Cut a small piece of foam / pipe insulation and tape it to the outside of the holders bottom section. It only has to be a small piece aprox 3 X 4 1/2 inch. It should be longer than the bottom section of the Gadjits and extend to bottom of your auto's holder (for leverage). It does not (and probably should not) wrap all the way around the cup holder. A scrap piece of 3/4 inch pipe foam insulation from a hardware/yellow box store ($1 for a 3 foot section) and black plastic electrical tape works perfect. This allows holder to be held firmly in place but easily removed and reinserted with no damage to car -- and it will NOT tip over OR out of auto's holder with a large drink or cup with handle. This modification make the Gadjits holder perfect.
Review: Works for me but sharp edges and wobbly - I like these for my kid’s water bottles that are just slightly too big for the backseat drink holders. My husband had to file them down bc the edges were sharp. I had to add big pieces of rubber from a tractor toys to help them stay in the backseat cup holders. They are still wobbly and come out sometimes but serve my purpose. Not sure if the backseat cup holders in my car are different from the front seat. They could work better in the front, I haven’t checked. I gave 4 stars bc they work and price was 1/2 or less than others that might work better.

### ⭐⭐⭐⭐⭐ Great cup holder expander
*by P***E on March 23, 2022*

I got a new, slightly larger phone and all of a sudden it didn't fit safely in any of my stroller caddy area. I came upon this cup holder expander and I was hoping that it would work. It does! Just two complaints. First, it's not stable in the cup holder. I had to wrap a cloth around the base and tape it in place so that it sits snuggly in my cup holder. This isn't a big deal, but it was a bit of a hassle, and I wish it came with some sort of gasket to make it fit snug and not rattle. Second complaint is that my fingers have to fit in a small slot between the handle and the expander. Unfortunately, this product has slightly sharp edges, which hurt my fingers. I wish the edges were smooth. Other than that, I am happy.
