I've been looking at a kidrunner for awhile, so I was excited to have the chance to test this out. I ordered the hands free, pull behind running kit separately. I'll start with the cons and why I only gave it 3 stars....First, the price. By the time you buy all of the attachments you need, you're better off just buying a bike trailer or kidrunner. Second....just using as a jogging stroller is useless for me. It only has a FIXED WHEEL. There's no option to make it a swivel wheel, like I can with my bob revolution. My neighborhood (where I typically run) is not straight. There are a lot of turns and culdesacs. In order to turn, I have to tilt back on the stroller and lift the front wheel up. Not easy if you have no upper body strength and it takes away from my focus on breathing. It also tends to veer to the right for me , so I kept having to tilt back to adjust, even on a straight shoot (even after "adjusting" the knob on the front wheel). Third con is that the straps are pretty cheap for the overall price of the thing. They are very thin webbing and I can see it fraying or wearing out very quickly. Last con, is that it has a 45 pound weight limit. Even my skinny 3 year old is 37 pounds. And my 2 year old is 36 inches and her feet fill up the entire space, so any kid taller than that will have to have their legs bent up. Now on to the pros: I LOVE the hands free jogging option. I have no upper body strength and I'm trying to get back in better shape. Before kids, I ran 6 miles several days a week. I have a Bob revolution (that I do love), but having to steer and focus on breathing is tough (like I mentioned above, my neighborhood is winding). It's also easier for me to take my dog out with me....before I'd have to hold the leash and the stroller and my dog kept running on the side of the stroller and running into it. Now, I can pull a kid behind me and the dog can run at my side. Steers VERY easily on the pull behind hands free kit. It's a little long, overall, so it's kind of like steering a 5th wheel. You will struggle in tight space, but in my neighborhood, it's fine. It has a pocket in the back for my things and a few mesh pockets on the inside for my kid's cup. I love the shade and mosquito net to fully enclose my kid. With them behind me, I can't see what's going on...I feel the full enclosure gives an extra layer of safety if they manage to Houdini out of the straps. The seat is padded, which is great for longer runs, but again, the straps are kind of cheap. It does have padded shoulder pads, though. Overall, It's a decent pull behind trailer, but if that's all you're using it for (like me, go with kidrunner for a much cheaper price). Using it as a runnign stroller won't work for me with the fixed wheel.
