I did a lot of research on a jogger that was sturdy enough to use for running so when my buddy boy worn out he could still tag along for the rest of the miles. This would have received all 5 stars however the one of the tires went flat the 1st day, I'm sure it's an easy fix and this does happen, but for the money spent I was bumped I have to immediately replace a tire tube. Other wise he loves his new rides, Lou weighs around 20# he has plenty of space and as you can see is so comfortable he climbed in and took a nap after assembly. It appears to be a smooth ride for him as we run along country roads which are far from perfect. Whether you're looking to just walk or run we are happy with our choice...ps. I also like the bright color and reflectors, we tend to hit the roads when its dark so this helps us be more visible to on coming traffic.
