Mine just arrived. It was easy to snap on the wheels and cup holder. The zipper was easy to use, no pulling or sticking. It's a good size for my 2 small dogs and will hold their weight. The non in the bottom is smaller than I expected but nice, I'm still trying to learn to collapse it. The wheel lock are easy to use and release. The mesh in front and back looks great. I hope I can remove and carry the top portion, but we'll see. So far, I love it
