I happen to own one. I have owned this paticular model for quite sometime now. I bought it when my daughter was about a year and a half old, and she's going to turn 4 in august. I have owned several strollers in the past, and have expierenced several more during the course of my younger siblings life as babies themselves. this is by far the most lightest and portable, and for it's lightweight construction the most durable, I still get a little carried away while walking my daughter down to the park. I treat it like a stroller of it's kind should not be treated, my daughter is reaching the 40 lb. mark and I noticed yesterday the max weight is only 35, I figured by now the tires would have fallen off by now, or at least the frame to snap somewhere in the "joints". It has held up beyond my expectations to say the least. My only complaints are that it needs to be taller. Since I'm 6'3" I tend to hunch over a little bit and puts a slight strain on my lower back. That and the tires and rims could be bigger so they dont get stuck on the slightest hole, or cracks in the side walk or dirt trail, since my family does alot of fishing. One last thing shoulder straps could be more helpful since like to see things around her. There may be some parents out there that are afraid of their kids falling out, and that's they passed on this model.
