I received stroller today. It literally took me 10 minutes to put together. Didn’t even need to read the instructions. Not bad for a female! Pretty simple. Appears to be good quality. I have a 15 pound Shih Tzu that fits perfectly. Plenty of room to move around. The tires are made of rubber. The stroller itself is quite large. Opens and closes with push of button. I haven’t used it yet to make a sound review, but will definitely use it tomorrow to see how it maneuvers about.
