I could not decide between this stroller and another one. So I bought them both to compare. These are My personal pros and cons I found for this stroller. They may not all pertain to you. I wouldn't say they're deal breakers at all. But this was in comparison to another stroller.Pros:1. fairly lightweight for a good quality stroller2. Opens and closes very smoothly3. Easy to operate closure mechanism on handle4. Full screened in viewing area is nice for pet if they like to turn around in the stroller5. Zipper operates smoothly, once you get it started6. Appears to be good quality and sturdy7. Cupholder is well-made and actually stays on the stroller8. Very roomy. Even with my 11 pound cat, I could easily put one of my other cats in there with it. Plenty of room for your pet to stand up or turn around in the stroller9. Very easy assembly. All you need to do is snap the wheels in place and snap the cupholder onCons (for me):1. Wheels do not move as smoothly or turn as nicely as my comparison stroller. It requires a little bit more effort to push or turn2. Zipper is not attached to itself at the end. The way it is designed it's kind of confusing figuring out how to start the zipper. Just try not to unzip it that last half inch3. The fact that it has a zipper is harder for me. One of my cats weighs about 11 pounds. While the zipper operates nicely I found with my last stroller that after a while the weight from my cat affected the performance of the zipper. I chose a no zip stroller insteadI could still recommend the stroller to anyone who decides to buy it in spite of the fact that I did not personally keep it. It's a nice quality stroller, and I had a really hard time deciding between this one and the other one.PRO TIP: on the off chance you have to return the stroller for any reason make a note or take a picture of the way It is packaged as you remove it from the box. It is extremely hard to get the wheels that are on an axle back into the box once it is unpacked.
