I recently got my hands on these universal stroller cup holders, and I have to say, they're a bit of a mixed bag. On one hand, they're incredibly convenient for keeping my drinks within reach when I'm out with my baby. The 360-degree rotation is a nice touch, allowing me to adjust the angle easily whether I'm pushing the stroller or taking a quick sip.

The installation was a breeze—no tools needed! I just clamped them onto the stroller's side bar, and they held up pretty well during our park visits. They fit most of my cups and tumblers, though I did notice that larger bottles (like my 20oz water bottle) wobble a bit if the stroller hits a bump. Not a dealbreaker, but something to keep in mind.

Where these holders fell short for me was on my bike. Like one of the reviewers mentioned, the frame just isn't sturdy enough for bicycle use. My water bottle kept slipping out during rides, which was frustrating. So, if you're looking for something for your bike, you might want to skip these.

Overall, they're decent for strollers or walkers—lightweight, easy to mount, and practical for everyday use. Just don't expect them to handle rough terrain or high-speed biking adventures!
