There are not many good places to attach this bottle holder to. When I attached it to the main bar that you use to push the stroller and place any weight on the water bottle holder the holder rotates on the foam grip and does not stay upright.
I had this holder for a few months before I lost it...because it falls off every time I fold the stroller. I also found that very few cups worked well in it, it would just flip over if the mug or bottle was skinny and tall (which is most bottles...). Not super impressed although I love my stroller!
Good quick easy purchase
Happy with speed of delivery and ease of purchase. Cup holder was pretty expensive tho, even compared to other brands. Otherwise great tho
